	HB Series SYNCHRONOUS MOTORS:
REVERSIBLE, INVERTED ROTOR, HYSTERESIS SYNCHRONOUS

HB Series are availabel in three direct drive synchronous speeds: 1800 RPM (1/35 HP), 1200 RPM (1/70 HP), and 900 RPM (1/115 HP). Inverted rotor design providing superior angular velocity characteristics reduces "flutter" to a minimum. Sealed ball bearings and machined die cast housing are standard. Models listed are designed for 115V, 60 Hz operation. A capacitor is required for operation.

900, 1200 or 1800 RPM Hysteresis Synchronous
