Quality parts start with the machine tool’s motor. Servo motors are the choice for axes motion control in machine tools built for high-speed, high-precision work. Factors like superior torque, high-resolution movement and feedback, and stability help avoid results like poor surface finish, accelerated tool wear and out-of-spec contouring.

Stepper motor torque decreases with rapid acceleration and at high speeds. Thanks in part to the powerful rare earth magnets they employ, servo motors maintain nearly all their torque at maximum speed, which also translates to higher efficiency. Some servo motors are also capable of nearly doubling their rated torque for short periods, which can be extremely useful for stopping, starting and reversing tables or spindles.
