5 mm brushless dc gearmotor

Ringwood, N.J —RMB Miniature Bearings has integrated its 5 mm "smoovy" brushless dc motor with two smoovy planetary geartrains. The SPH50003 gearmotor comes with an 125:1 ratio. Continuous torque of 1.5 oz-in. at gearmotor shaft speed of up to 160 rpm provides smooth and high efficiency operation (60%) for a wide range of application.

Ringwood, N.J —RMB Miniature Bearings has integrated its 5 mm “smoovy” brushless dc motor with two smoovy planetary geartrains. The SPH50003 gearmotor comes with an 125:1 ratio. Continuous torque of 1.5 oz-in. at gearmotor shaft speed of up to 160 rpm provides smooth and high efficiency operation (60%) for a wide range of application. The eeartrain of the SPH5004 has a ratio of 25:1. It is based on the same brushless dc motor and provides 0.33 oz-in. of continuous torque at shaft speeds up to 800 rpm. Overall gearmotor axial length is 0.848 in., and both can withstand momentary radial loads of up to 89.9 oz on the 0.055-in. OD shaft. Operating life under normal contitions is up to 1,000 hr.
