Single Phase Synchronous Motor

Application

Reversible power drive for actuators, pumps, label printing machines, medical and optical equipment, office machines, automatic vending machines, machine automation

Description

MTR7a is a single-phase synchronous motor. It offers operating voltage options of 12V, 24V, 48V, 110V, and 230V. It delivers 250 RPM speed and 7.2 Ncm torque while maintaining 50/60Hz rated frequencies.

This motor can combine with spur gearboxes to customize torque and speed outputs as required. The MTR7a's precise synchronous motion control makes it well-suited for industries such as Pumps and Actuators, and other applications needing accurate bi-directional positioning.
