Product Description

8mm Single Shaft Nm Nema 34 Closed Loop Stepper Motor

      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.

4. How close loop stepper motor works:


The most advanced closed-loop stepper control method is to operate the motor as a two-phase brushless (BLDC) motor. (Note that many stepper motors have two phases offset by 90° whereas brushless dc motors have three phases offset by 120°.) This method is referred to as servo stepper or closed-loop stepper control.

With servo control for stepper motors, instead of the drive providing full current to the motor to produce movement, feedback from an encoder detects the shaft position, and a control loop (typically a PID loop) determines the exact torque needed for the shaft to follow the move profile. In other words, the motor is driven by a torque command rather than by pulses of current.
