Nema 34 Closed Loop Stepper Motor Systerm High Torque 4.5N.M Easy Servo Motor For Milling Machine
Like stepper motors, servo motors have many implementations. Let’s consider the most common design, which incorporates a rotor with permanent magnets and a stationary stator with the windings. Here too, the current creates a magnetic field distribution that acts on the rotor to develop torque. Servo motors have significantly lower pole counts than stepper motors, however. As a result, they must be run closed-loop.
In general, servo motors are more sophisticated than stepper motors. They run significantly faster than stepper motors, with speeds on the order of several thousand RPMs . This enables servo motors to be used with gearboxes to deliver much higher torque at useful speeds. They also deliver more consistent torque across the speed range of the motor. Unlike stepper motors, they do not have holding torque per se.
