Complete Motion Solution

For a complete motion solution, the RPX52 is compatible with ElectroCraft's Universal and PRO Series drives.

High torque density. Excellent torque per frame size performance.

New from ElectroCraft, the RPX52 is a highly dynamic and controllable very small frame metric motor. With an advanced 14-pole encapsulated core, this compact DC motor offers high torque density at a very affordable price. The RPX52 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 RPX52 include hall sensor feedback and can be configured with an optional encoder (differential, optical encoder with up to 5000 lines).
