Leeson P300 DC Gearmotor, 1/20 HP, 5 rpm, 12VDC Armature, 30 Frame, TENV

Features

• SCR rated gear motors totally enclosed, permanent magnet DC gear motors, performance matched for continuous duty service over a 60:1 speed range
• 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
• Precision machined in-line steel gears
• 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
• Optional conduit box and PZ gear motor mounting bracket available
• These gear motors 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
• Motor's stall torque could exceed recommended full load torques. a current limiting device such as an SCR control should be used to prevent damage, this issue is even more critical for low voltage motors, typically no controller is used since motor is connected directly to a battery, so some type of current limit or fusing should be considered
• Overhung load capacities shown are at center of output shaft
