	SYNCHRONOUS MOTORS: DA and DB Series
REVERSIBLE, HYSTERESIS SYNCHRONOUS

Heavy duity DA abd DB Series gear motors maintain timing accuracy and are offered in a very broad range of shaft speeds from 120RPM through 24 RPD. These motors are recommended especially for applications requiring high gear torque ratings (100 oz-in maximum) and small size (DA case size: 2 1/2" dia. x 1 3/4" depth). Add 1/4" to depth for DB case.

Gear trains are of the same high-quality components and construction as described for the EA and CA Series. All motors are reversible. Models listed are designed for 115V, 60 Hz operation, a capacitor is required for operation.
