    3 tips for replacing stepper motor with servo motor

    1. To ensure that there is not too big change in control system, it is suggested to choose digital servo system, which can still use the original pulse control method.
    2. As the overload capacity of servo motor is strong, 1/3 of original stepper motor rated output torque can be as reference to determine the servo motor rated torque.
    3. Since the rated speed of servo motor is much higher than stepper motor, it is better to add a deceleration equipment, so as to make servo motor run at rated speed. To reduce the cost, it is also feasible to choose the motor with smaller power.

    Existing reviews of 4 hp (3 kW) AC Servo Motor, 15Nm, 2000rpm
    Excellent and affordable servo motors
    These are excellent and affordable servo motors. Both 3 kW of them rotate very well. Great fitting for the class projects I needed them for. I am happy with my purchase.

    Need a servo drive with this motor
    Do you have a preferred servo drive for use with this 3 kW 2000 rpm servo motor? Thanks.

    Dear friend, you can refer this one (AC Servo Drive for ATO Servo Motor), see the specs on:
    3 KW AC servo motor brake function
    I wanted to confirm the functionality of the brake on the 3KW AC servo motor. We want a brake that will engage when power is off. From the data sheet this seems to be true but I need to confirm because in our application it is critical that the brake engages in the case of sudden power loss.

    Yes, when power is off the servo motor will be brake.

    AC Servo Drive for ATO Servo Motor

    SKU: ATO-MG1000
    AC servo motor drive, 220V single phase or three phase input, 380V three phase input, is a great fit for applications requiring position, speed, and torque control methods. All the power rating range from 50w to 8.6kw of our ATO brushless AC servo motors will work perfectly with this type of servo drive.
