The ES-MH342120 is a 12 Nm (1,700 oz - in) 3 phase NEMA 42 stepper motor with integrated 1,000-line incremental encoder. It is built with high quality material and can move smoothly with high precision, very low noise & heating.

When driven by Leadshine ES2-3DA2306 easy servo drive, the position loop between the motor and drive is fully closed. Therefore, loss of steps which limits adoption of stepper systems is totally eliminated. Because there is no torque resolution needed like in open loop stepper systems, high-speed performance can be improved up to 30% over open loop stepper systems. Hybrid stepper systems are also ideal to replace brush-less servo systems in CNC or machining operations as they provide huge starting and low speed torque.

The ES-MH342120 easy servo motor can also be driven by regular open loop 3-phase stepper drives, and output encoder signals to motion controllers, or external devices.

This NEMA 42 frame motor is 110 mm square on the face, with four 4 mm diameter untapped holes.
