AC Motors & Gearmotors


Clutch & Brake MotorsClutch & Brake AC Motors

This compact, precision AC motor is equipped with an internal clutch and brake mechanism for use with a gearhead. This combination makes it the ideal motor for applications involving frequent START/STOP operation, positioning, indexing, jogging and incremental feeding. CB motors have a 3.54 in. (90 mm) frame size and come in output powers of 40, 60, 90 W (1/19, 1/12 and 1/8 HP).

Suitable for High-Frequency Operation

The combination of a constantly rotating induction motor and a clutch and brake unit enables high-frequency starting and stopping.

Characteristics of CB Motors

The CB motor is designed so that it runs continuously. This gives the advantage of quicker response time and higher torque in order to move the load.

Output shaft rotation is controlled through the use of the clutch and brake mechanism. The load is stopped by disengaging the clutch and applying the brake. The motor is always affected by the rotor inertia. However, with a clutch and brake unit, the load is not affected by the rotor inertia.

For these reasons, CB motors boast superior response over other AC standard motors, starting and stopping in considerably less time.

To meet high-frequency, starting and stopping applications, Oriental Motor uses an induction motor for its continuous duty rating. An induction motor is best suited for uni-directional movements. The CB motor is not suitable for frequent bi-directional starting and stopping motion.

Compact and Easy to Handle

The compact design simplifies handling and enables the drive unit of the machine to be mounted in a small area.

Highly Reliable Gearhead Employed

GC-type and GCH-type gearheads are specifically designed for the CB motors and boast excellent impact resistance, greater strength and high reliability.
