Why my stepper motor is not working?
You see Stepper Drivers provide current to each coils of a Stepper Motor and those current are switched back and forth to make the Stepper Motor rotate. So when a connection to one of the coils gets disconnected it creates a spike (current/voltage) that gets feed back to the Stepper Driver and can cause failure.
Can a stepper motor stall?
Stepper motors are robust and are used in many motion control applications. The motor will stall if the error between the commanded position and the rotor position exceeds two full steps.
Can you manually turn a stepper motor?
Normally, you can easily turn a stepper motor shaft by hand, and you can feel each of the 200 ‘detents’ as you rotate the shaft.
Can a stepper motor be repaired?

How long does a stepper motor last?
The typical lifetime for a stepper motor is 10,000 operating hours. This approximates to 4.8 years; given the stepper motor operates one eight-hour shift per day. The lifetime of a stepper motor may vary in regards to user application and how rigorous the stepper motor is run.
Is stalling a stepper motor Bad?
In some cases, stalling of a stepper motor causes a large voltage spike that often damages the phase transistors on the driver. Some drivers are designed to protect themselves from such occurrences. If not, Transient Suppression Devices can be added externally. Consult the factory for further information.
What causes stepper motors to skip?
There are 3 main reason for a stepper motor to skip (loose) steps: the motor have not enough power to drive the forces applayed to his axle. Change the motor or drive current or microstep or decrease the force to drive.
