RPX32 Brushless DC Motor
RapidPower™ Xtreme Series

Summary Details

Size: 32mm (1.26in)
Peak Torque: to 438 mNm (62 oz.in)

High torque density. Excellent torque per frame size performance.

New from ElectroCraft, the RPX32 is a highly dynamic and controllable very small frame metric motor. With an advanced 8-pole encapsulated core, this compact DC motor offers high torque density at a very affordable price. The RPX32 is available in 12V, 24V and 48V versions and like all ElectroCraft motors is fully customizable. This versatile motor is highly energy efficient and ideal for embedded applications.

All versions of the RPX32 include hall sensor feedback and can be configured with an optional encoder (differential, optical encoder with up to 2048 lines)
