One of the major problems with a stepper motor is complete motor failure. This problem is caused by excessive current being sent to the device by the power supply. A short circuit in the wiring from the power supply to the motor cause this problem with the stepper motor. Some application will cause this short circuit.
Why stepper motors lose steps?
The reason is that the input of the motor power is insufficient and the torque generated cannot keep up with the rotor speed of the stator magnetic field, resulting the step loss. … The rotor gains too much energy in the stepping process, resulting in the torque generated by the motor is too large and motor stepping.
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.
Do stepper motors wear out?
Since a stepper motor has no brushes to wear out, its life usually far exceeds that of other mechanical components in a system. If a stepper does fail there are certain components which are likely to be involved.
How can I make my stepper motor run smooth?
Smooth operation at low speeds with consistent torque is possible using stepper motors and drives. It is accomplished by ensuring the drive and motor work together, and often by using microstepping. Microstepping is driving the stepper motor such that each pulse does not complete a full step.
How do I know if my stepper driver is bad?
The first sign of overheating is erratic stepper motor behavior. Typically, this can be recognized by the sounds of the stepper motor suddenly losing power (thermal shutdown). If no load or movement is required of the motor, it is hard to detect whether it is over-powered as the driver is barely producing any heat.
Can stepper motors run continuously?
Stepper motors fall somewhere in between a regular DC motor and a servo motor. They have the advantage that they can be positioned accurately, moved forward or backwards one ‘step’ at a time, but they can also rotate continuously.
How can I speed up my stepper motor?
There are a few main ways to increase your maximum step speed:
- Use a higher voltage. …
- Set the current limit to the maximum allowed by your stepper motor. …
- Ramp the stepper speed up slowly. …
- Decrease the external load on the stepper.
Do you need to oil stepper motors?
Do not oil the X or Y stepper motors. The only motor that requires lubrication is the Z-motor and lead screw combination. … Oiling the stepper motors can permanently damage the motors.
Do you need to lubricate stepper motors?
When it is all about reducing the friction of a stepper motor, there is a necessity to lubricate or grease the bearings. FAULHABER PRECISTEP SA proposes different lubricants, oils or greases to facilitate the movement of the motor and obtain the best performances in any environmental condition.
