1/20HP LEESON 19RPM 90VDC OS300 SERIES PARALLEL GEARMOTOR M1125250

LEESON M1125250.00, P300 SERIES OFF-SET, DC SCR Rated, totally enclosed, permanent magnet SCR rated DC gearmotor, performance matched for continuous duty service over a 60:1 speed range. All have constant torque throughout the range when powered by a full-wave unfiltered SCR-type adjustable speed control having a typical form factor of 1.3 to 1.4.

Mechanical Specifications:
Precision machined in-line steel gears, with a first stage steel helical gear followed by spur-type gears. Lubrication is permanent semi-fluid grease, reducing possibility of leakage. Output shafts have needle bearings for high load capacities. Shafts are hardened steel. Conduit Box not included with motor.

Application Notes:
These gearmotors are designed for mounting at any angle, but motor below the reducer should be avoided to prevent leakage of lubricant into the motor should the motor shaft seal fail. Overhung load capacities shown are at center of output shaft.

The motor’s stall torque exceeds recommended full load torques. A current limiting device such as an SCR control should be used to prevent damage.
