CP Automation set to integrate new resistor ranges

Service and supply of drives, VSDs, Inverters, controls and braking resistors~ Service and maintenance specialist increases its focus on the elevation, crane and OCH sectors ~

Service and maintenance specialist CP Automation has announced that it will be improving its product offering for the elevation, crane and OCH industries by adding Cressall Resistor’s HP and ES series braking resistors to its portfolio. The relationship with Cressall is now well established and compliments CP Automation’s range of independent supply relationships with manufacturers of inverters, PLCs and other electronic equipment and control systems.

First in CP Automation’s range is Cressall Resistors’ HP series of high performance dynamic braking resistors (DBRs). The new range is ideal for use on cranes, winches, conveyors and test loads as well as on lifts and elevators. These compact, ready boxed DBRs are enclosed to IP20 and make virtually no noise when subject to inverter braking currents. Their low inductance open-wound element construction allows high power-dissipation in a small space. It is these two factors that make the HP series ideal for use in lifts and elevators where noise and heat dissipation are both significant issues. When used with an inverter, the units are suitable for use with any make of drive.

The range is divided into HP1, HP2 and HP3 units, which have continuous power ratings of 1.5kW, 3.0kW and 4.5kW respectively. The continuous power ratings can be exceeded when power is applied for less than 100% of the time and the extent to which this can be done is calculated using a simple equation.

Also available is Cressall Resistors’ rang of low noise ES braking resistors, which has recently been expanded with the addition of 1.0 and 2.0kW sized models. These new ratings complement the existing array, which includes 0.6, 1.5, 3.0 and 4.5kW versions with resistance values from 3.9Ω to 330Ω. The new 1.0 and 2.0 kW sizes are used where there is the need to cope with high levels of regenerated energy in a compact space. This includes motor control on elevators, VSD control and use on conveyors, cranes and winches as well as test loads. Like the HP series, these robust IP20 rated units produce negligible audible noise.

Both sets of resistors are manufactured using high grade nickel chrome wire, which means the resistance value changes only negligibly over the temperature range of the element. “This is a significant factor,” explained CP Automation’s director Tony Young, “because a design using lower grade stainless steel could increase in resistance by as much as 50% - resulting in impaired braking.”

RevCon saves energy and money and helps meet green targets for elevators owners

Service and supply of drives, VSDs, Inverters, controls and braking resistors~ New product returns energy to the grid more cost effectively than other available systems ~

Independent maintenance consultancy CP Automation has teamed up with German electro-technology specialist, Elektrotechnishe Anlagen to provide UK sales for RevCon - a new product for returning to the grid the energy produced when a motor slows down. CP Automation expects RevCon to take the elevation industry by storm; because the motors driving elevators are required to brake constantly as the lift slows down and stops.

RevCon will work with any AC drive and is much more cost efficient than using two inverters to achieve the same effect. Furthermore, the product features a harmonic filter as part of the package, which ensures that the electricity returned to the network is fit for purpose and G5/4 compliant. A CP Automation spokesmen explained that there a several prestigious elevation projects in the UK that are already planning to install the product.

RevCon uses a feed-in tariff, similar to those used on domestic and semi commercial wind turbines, to allow the customer to charge the electricity supplier for the returned power. However, Tony Young, a director of CP Automation explained that, while RevCon isn’t a similar product to a wind turbine, the analogy is useful in outlining its efficiency. “A wind turbine isn’t particularly effective, normally operating at about 40% efficiency,” explained Young. “In contrast, when a motor slows down and begins to generate electricity, RevCon will operate at around 90% efficiency.”

“However, the bottom line for most businesses is the commercial imperative and this is where the product really comes into its own. The cost savings can be quite extensive in a facility where there are several lifts and escalators. This is the most compelling argument to present to the board!”

As well as acting as sales agent, CP Automation also offers advice on the overall project as well as repair and maintenance on motors, inverters, resistors and other peripheral products such as encoders. The company also provides replacement equipment when repair is impractical or not possible. In these instances, CP Automation’s independence comes to the fore – allowing it to stock a range of products from all the major motor and inverter manufacturers. Indeed, replacement inverters, encoders and motors are normally installed in a matter of days.

Automation firm appoints new sales expert

Service and supply of drives, VSDs, Inverters, controls and braking resistors~ Passionate environmental campaigner also highlights the history of woman in automation ~

Field service and maintenance specialist CP Automation has appointed long standing industry expert Jennie Gordon to the role of product sales manager. The new position will encompass both the CP brand and sister company Euroserv. Gordon has been in the automation industry since 1989, a time when there were few women in this niche of the once male dominated engineering industry.


Before joining CP Automation, Gordon worked for Betech Systems, a UK distributor for Baldor. Gordon explains, “I first joined Betech in telesales. But I take pride in knowing all about the thing I’m selling, so in the evenings I used to read American electric motor manuals. After three months I was offered a job as an internal sales engineer and later I moved into external sales, where I spent twelve years. My last role was as corporate sales manager.” Gordon went on to work for Coulstock & Place Engineering, her last position before joining CP Automation.

Gordon believes that the biggest highlight of her career has been making men understand, at board and shop floor level, that women have valuable engineering expertise to offer. “When I first moved into the automation industry, I encountered untold opposition. At that point there simply wasn’t the quantity of female engineers that we have now. Today, most people think it’s unusual to encounter a female engineer of my age but that hostility has gone in most places.” Gordon also includes tripling turnover at Betech amongst the experiences that have stayed with her throughout her career.

When asked about the standards of the industry in which CP Automation operates, Gordon responded with a passionate argument in favour of improving UK Plc’s environmental credentials. “I’m a green person and I think we waste too much in industry. Every business should invest in high efficiency motors run by inverters that will save energy. If everybody changed their EFF2 motors over to EFF1 motors we would see a phenomenal decrease in energy used. The same applies to fitting automatic sensor lights as a standard part of lean manufacturing initiatives.”

Gordon’s hopes for her time at CP Automation are simply to increase sales, although with typical ambition she argues the potential for this increase is ‘exponential’. “The thing about CP Automation is that its young company, with real ideas, argues Gordon. “It provides its staff with the backing to carry on doing what they are good at; it wants to develop its employees and help them develop the company in turn.”

Gordon is a funk jazz fan, and has a broad ranging interest in other kinds of music. Despite originating from Lancashire, she lives in Halifax, West Yorkshire and holidays in England. She believes that even as a sales engineer who constantly travels the UK, there are still countless sights to be seen within the country, further reinforcing her green credentials.

Keep it simple without a keeper

Service and supply of drives, VSDs, Inverters, controls and braking resistors~ CP Automation announces service and repair technique ~

Field service and maintenance specialist CP Automation has announced a service and repair technique for DC drives, attached to permanent magnet motors, that is set to make in-house re-setting of the serviced drive a thing of the past. The technique dispenses with the use of a ‘keeper’, which normally acts as a substitute for the armature in the servicing procedure. Instead, the company de-magnetises the motor before repair and then re-magnetises it afterwards to the correct setting.

The company utilises a set of specialist tools, including a magnetising cabinet, as well as intellectual property built up over decades in the drives industry to apply the new technique.

The reason that the settings on DC drives attached to motors that have been serviced or re-wound in their lifetime are often incorrect is that there is something unique to be borne in mind when repairing or servicing a DC permanent magnet motor. The standard philosophy within the rewind industry is to remove the armature and replace it with a ‘keeper’; to stop the levels of the magnets degrading. However, older magnets, and the material used to manufacture some newer magnets, will degrade while the armature is being removed and the keeper is being put in its place. The same applies when the armature is put back in after repair or service. The result is increased RPM and lost torque, which may mean the motor draws more current, costing money and creating a greater environmental impact.

If the CPA process isn’t used, an in-house engineer has to re-set the DC drive to cope with the changes to the motor. As a result, all the systems in the plant eventually become unique and cease to be interchangeable. The only solution is to de-magnetise the motor before repairing it and then re-magnetise it to the correct level afterwards, as CP Automation does. The company derives the calculation for this from the speed and EMF (Electro Motive Force) settings on the name plate of the motor.

“Plant managers want to swap equipment around in the event of a breakdown or maintenance issue,” explained Tony Young, a director of CP Automation. “However, they often find that the DC drives attached to permanent magnet motors on different production lines have different settings – making it hard to interchange things easily. Our solution means that that the settings will be exactly as specified on the name plate, meaning they can be swapped around easily.”
