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.
