ES-M23440 is 4.0 Nm (566 oz-in) 2 phase NEMA 34 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 2 phase ES-D  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, 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 torques. You can get more information on Leadshine Easy servo Products page.


Leadshine ES-M23440 easy servo motor can also be driven by regular open loop 2 phase stepper drives or multi-axis stepper drives, and output encoder signals to motion controllers, or external devices.
