Leadshine ES-MH234120 is an 12.0 Nm (1,700 oz-in) 2-phase NEMA 34 stepper motor with 1,000-line incremental encoder (A , A-, B , B-. Indexing signals optional).


By adopting unique design and built with high quality material and special design, ES-MH234120's motor heating is more than 20° lower than comparable normal stepper motors when operated at 110/120 or 220 / 230 VAC voltage. It can move smoothly at high precision with very low noise.


When driven by Leadshine 2 phase high voltage input ES-DH series easy servo drives with direct 110/120 input voltage, the position loop between the motor and drive is closed. Therefore, loss of steps which limits the adoption of open loop stepper systems, is totally eliminated. Such systems are also ideal to replace brushless servo systems to offer huge starting and low speed torques. You can get more information on Leadshine Easy servo Products page.


Leadshine ES-MH234120 can also be driven by regular open loop 2-phase stepper drives and feed back encoder signals to the motion controller, PLC, or external device. Its extra low motor heating feature can offer improved performance for the control systems in your applications.
