The RJW High Frequency Division has a range of products and services dealing with a range of plant and machinery operating above the standard electrical frequency (ie 50Hz).
We supply, repair and support a range of equipment including grinders, high frequency motors and frequency changers.
Commonly used by the wood-working industry, the best known makes being Perske, Homage, Elte and Wadkin, high frequency spindle motors, due to their characteristics, require specialist attention during the repair process. RJW has the skills, experience and equipment to carry out the best possible repair improving reliability and service life. The stators in all high frequency motors are vacuum impregnated following rewind and all rotors are dynamically balanced to ensure smooth running and minimise vibration. Special attention is also paid to the replacement bearings used in these units. We also hold a number of parts for Wadkin and Perske motors.
All high frequency motors are tested at the rated frequency and voltage to ensure conformance to the original specification.
Reconditioned high frequency motors are also available should motors be beyond economic repair following inspection or spare units be required.
