Features

• 3-Phase NEMA 42 frame size
• 2800 oz-in (20.0 Nm) holding torque
• Speed range: 0-2,000 RPM
• Integrated 1,000-line (4,000 CPR) Incremental Encoder with A , A-, B , and B- signals
• Strong 19 mm shaft
• Quiet movement and low motor heating

ES-MH342200 is 20 Nm (2800 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 a Leadshine 3 phase ES-DH  easy servo drive to take direct 110 / 120 / 220 / 230 AC input voltage, 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, you can much better high-speed performance than open loop stepper systems by increasing up to 30%. Such systems are also ideal to replace brushless servo systems to offer huge starting and low speed torque.
