Adjusto-Spede systems deliver a 34:1 speed range at 250% rated torque, making them ideal for high-load startups. Because Adjusto-Spede drives differ significantly from standard motor types, they require specialized knowledge and equipment. A&C Electric technicians have decades of experience repairing industrial electric motors and strive to save customers money by reducing lead time and spare motor costs.

Our team repairs and refurbishes Adjusto-Spede industrial motors using precision tools, proper handling techniques and decades of hands-on experience. Each motor is returned quickly and at a significantly lower cost than replacement.
