Overview
The Kpower P0037 is a coreless micro servo motor for RC airplane control mechanisms where low weight and compact dimensions matter. It weighs 3.7 g, measures 19.8 × 8.2 × 22.2 mm, and operates from 4.8–6.0 V. A plastic case and POM gears keep its construction lightweight, while voltage-specific torque and speed ratings help you select a suitable supply for your control setup.
Features
- Coreless motor in a compact micro servo format.
- Plastic housing with POM plastic gears.
- 20T output spline with a 3.6 mm diameter.
- 2 μs dead band width.

The voltage-unspecified values are separate ratings and should not be substituted for the voltage-specific values.
Applications
Use the P0037 to actuate RC airplane control linkages where a 3.7 g servo and a compact mounting envelope are important. Select the supply within 4.8–6.0 V and size the linkage load against the torque rating at that voltage.
