Keep it simple without a keeper

~ 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.”

CP Automation announces benefits of Cressall relationship

~ Service, maintenance and replacement specialist provides further client advantage thanks to association with UK’s largest resistor firm ~

CP Automation and Cressall Resistors have announced the formalisation of a long standing relationship between the two companies. The alliance allows customers to buy inverter and resistor packages quickly and with confidence in the sizing and speciation of the equipment. Accurately sizing a resistor, which is working in tandem with an appropriate drive package, can potentially reduce capital expenditure and increase efficiency with the resultant savings in operating costs.

CP Automation keeps a stock of Cressall products in all of its branches and, as a result, can react very quickly to customer requests. This is particularly beneficial because the UK resistor market has consolidated enormously over the last five to ten years, with the majority of the major players being absorbed, purchased or simply shutting down. As a result, only a few companies in the UK have the necessary stock.

“Before co-founding CP Automation, I actually worked for Cressall Resistors,” explained Tony Young, a director of the maintenance specialist. “I was part of the team that helped build the UK market to the level it is currently at. Partly as a result of my time there, there is a degree of trust between our two companies that is unusual in such relationships. It also means that our team can lend a high level of experience and knowledge of the resistor market-place to customers in the wider drives industry.”

Current CP Automation customers include OEMs such as Control Techniques, Yaskawa and SSD (formerly Eurotherm) as well as clients in most of the industrial application areas applying inverter control. “Over the years we have gained specification knowledge and experience in the drives industry that allows us to work well and easily in sectors ranging from printing to elevator control,” continued Young.

Peter Duncan, a director of Cressall Resistors, added, "Our business has undergone some extensive growth in the last two years. As well as merging TPR Resistors with Cressall we have also had considerable organic expansion. CP Automation has been of considerable benefit to us during this period.”

Service and repair specialist launches independent motor business

~ CP Automation opens Tyne & Wear based sister company ~

Field service and maintenance specialist, CP Automation has opened a new business specifically to handle the repair and sales of specialist motors, notably AC and DC servos. Called Euroserv, the new business will also deal with associated products such as inverters, resistors and encoders. The Tyne & Wear based business has already established client relationships with companies including Nissan, Rolls Royce and SIEMENS.

The new business is a source of mechanical expertise, which complements CP Automation’s existing in-depth understanding of electronic boards, PLCs (Programmable Logic Controllers) and AC and DC drives. The business was deliberately located in the North East in order to be close to customers and to tap into the expertise of key senior appointments in the area. On an ongoing basis the management team feels that the region offers the correct mix of available skills to allow for expansion of the business. Opening Euroserv entailed the creation of two new jobs in the local area as well as the deployment of some existing CP Automation staff.

“We opened this business to deal with the repair or economical replacement of motors from an independent standpoint,” explained Tony Young, a director of both CP Automation and Euroserv. “Too many maintenance and repair services focus on a single manufacturer. From an improvement perspective, this defeats the object. The best fit for any application may not always be the original piece of equipment that was chosen.”

The services offered by Euroserv include Megger testing of power output and input stages using a unique range of techniques for voltage leakage and short circuit testing. The company also offers V-I testing on all power devices for open circuit and temperature failures. Another service is the replacement of all power section, low voltage, high frequency electrolytic capacitors with 105C high performance low ESR units. Motors are also cleaned to negate the effects of dust contamination. Another option would be load, functionality and soak testing on an appropriate motor in industrial machine simulated conditions for extended periods of time.

Repair and replacement projects have already been completed on AC servo motors, DC servo motors, geared servo motors, AC brushless servo motors, AC spindle motors, router motors, standard motors, high frequency AC motors, DC shunt motors, printed circuit motors, tachogenerators and all types of resolver.
