Overview
The Kpower MM1500 is a metal-gear servo motor for RC models, robot joints and compact automation mechanisms. It operates at 4.8–6 V and combines a DC brushed motor, aluminum mid case and 25T output spline in a 40 × 20 × 37.5 mm body. Voltage-specific torque and speed ratings help match the servo to the supply and motion requirements of your mechanism.
Features
- Metal gears with a DC brushed motor.
- Aluminum mid case and 2BB bearing arrangement.
- 25T output spline for mechanical connection.
- 900–2100 μs control pulse-width range with a 4 μs dead band.
- 58 g body with a 20 cm wire length.

Applications
- RC aircraft and UAV mechanisms: actuate control linkages and retractable landing gear with voltage-specific speed ratings for motion planning.
- RC cars and boats: operate steering or other mechanical linkages; listed uses include 1/5-scale remote-control cars. The 25T spline provides the output connection.
- Robot joints and desktop robot arms: drive joint linkages using metal gearing, with the compact body helping integration into small assemblies.
- Educational robot kits and STEAM projects: build pulse-controlled motion mechanisms around the specified 900–2100 μs input range.
- Industrial equipment and automation: actuate compact mechanisms where the 40 × 20 × 37.5 mm envelope and 4.8–6 V supply range suit the design.
- Specialized equipment mechanisms: listed applications include underwater robots, smart toilets, medical endoscopes and medical equipment; the compact servo body supports integration into their mechanical assemblies.
