Product Details
The DC gearmotor is a robust parallel shaft unit featuring a power rating of 1/20 HP and an operating speed of 9 RPM, with a gear ratio of 216 to 1. It is designed to handle an overhung load of 474 pounds and provides a full load torque of 268 lb. in. The motor is totally enclosed and non-ventilated, classified as TENV, with a 30 frame size and operating at 90V with a name plate current of 0.54 amps. This permanent magnet DC gearmotor is performance matched for continuous duty and incorporates precision machined in-line steel gears, including a first stage steel helical gear followed by spur-type gears. It utilizes permanent semi-fluid grease for lubrication to minimize leakage risk, while its output shafts are equipped with needle bearings for high load capacities, and feature hardened steel shafts. While a conduit box is not included, the motor can be mounted at various angles, though it is advisable to avoid a shaft-up position with the motor below to prevent lubricant leakage if the shaft seal fails. The motor's stall torque surpasses the recommended full load torques, and a current-limiting device, such as an SCR control, is recommended to prevent damage. The Model 300 gearmotors share the same mounting dimensions as Bison's 300 and several Dayton gearmotors, ensuring compatibility with Bison model 011-336-1208, Bodine model 4147 (with a 90V DC armature voltage and 3-point mounting on the Leeson gearbox), and Grainger/Dayton model 6A194.
