DP221 GearMotor 12V
I.CH
22mm Reducer Motor
Square
Our 22mm 12V/24V planetary gear motors come with an optional encoder. Uniform load distribution minimizes gear abrasion and maintains quiet, low-noise operation. These DC planetary gear motors are ideal drive solutions for electric locks, miniature valves, medical instruments and compact automated devices. Also available in 16mm, 28mm, 32mm sizes.
Flexible torque and speed output with dual 12V/24V voltage options
Low noise & long service life with mixed planetary gears and built-in shaft ball bearings
Optional encoder support for precise positioning, multiple body length options
Full OEM custom modifications, ideal for medical devices, electric locks and small automation equipment

Frequently Asked Questions
A1: The DP221 22mm DC planetary gearmotor provides variable rated torque depending on different gear ratios. Higher gear ratios deliver larger output torque. We support custom torque output to fit your small automation equipment requirements.
A2: Small 22mm planetary DC gear motors are widely used in medical instruments, automatic window actuators, smart home devices, miniature automated machinery and other compact drive systems.
A3: Determine required output speed and torque first. Choose a low gear ratio if you need fast speed; select a higher gear ratio when greater torque is needed. Our engineering team can assist you with gear ratio selection.
