The CY Series is a precision DC motor available as motor only or with the GF Series parallel shaft and the C Series Inline gearbox. The CY is an ideal answer to applications requiring high torque and continuous or intermittent duty operation. Fitted with available encoder or tachometer options the CY becomes a very flexible DC solution.
