Our company's Stepper motor factory was established in 2008, with the most professional team, at the same time, we welcome customers to customize the design.The main features of stepping motor are:
1.Generally, the accuracy error of stepper motor is 3-5% of the step Angle, and it is not accumulated.
2.Maximum permissible temperature for stepping motor appearance.
High temperature of stepping motor will first demagnetize the magnetic material of the motor, which will lead to a decline in torque and even step loss. Therefore, the maximum allowable temperature of the motor surface should depend on the demagnetization points of different magnetic materials of the motor.Generally speaking, the magnetic material demagnetization point is in the centigrade 130 degrees above, some even as high as the centigrade 200 degrees above, so the stepping motor surface temperature in centigrade 80-90 degrees completely normal.
3.The moment of stepping motor will decrease with the increase of speed.
When the stepping motor rotates, the inductance of each phase winding of the motor will form a reverse electromotive force.The higher the frequency, the greater the reverse ELECTROmotive force.Under its action, the motor increases with frequency (or speed) and the phase current decreases, resulting in a decrease in torque.
4.The stepper motor can operate normally at a low speed, but it cannot be started if the speed is higher than a certain speed, accompanied by a loud noise.
The stepper motor has a technical parameter: no-load starting frequency, that is, the pulse frequency that the stepper motor can start normally under no-load condition. If the pulse frequency is higher than this value, the motor cannot start normally, which may result in step loss or stalling.Under load, the startup frequency should be lower.If the motor is to reach high speed rotation, the pulse frequency should have an acceleration process, i.e. the starting frequency is low, and then the desired high frequency is increased according to a certain acceleration (motor speed is increased from low speed to high speed).
Stepping motor plays an important role in digital manufacturing era with its remarkable characteristics.With the development of different digital technologies and the improvement of stepper motor technology, stepper motor will be applied in more fields.
