The accuracy of the general stepper motor step angle of 3-5%, and does not accumulate. Stepper motor OEM peristaltic pump allows the appearance of the temperature. Stepper motor temperature is too high will first demagnetize the motor's magnetic material, resulting in torque down or even out of step, so the motor allows the appearance of the temperature should be dependent on the demagnetization of different motor magnetic materials; Generally, the demagnetization of magnetic materials 130 degrees Celsius are above, and some even as high as 200 degrees Celsius, so the stepping motor surface temperature 80-90 degrees Celsius is completely normal.

torque will increase with the speed down. When the stepper motor rotates, the inductance of each phase winding of the motor will form a back electromotive force; the higher the frequency, the larger the back electromotive force. In its role, the motor with the frequency (or speed) increases and the phase current decreases, resulting in torque decline. Stepper motor OEM peristaltic pump can operate at low speed, but if it is higher than a certain speed, it can not be started, accompanied by howling. Stepper motor has a technical parameters: No-load starting frequency, that is, the stepper motor can normally start under no-load pulse frequency, if the pulse frequency is higher than this value, the motor can not start normally, may occur lost step or stalling. In the case of a load, the start frequency should be lower. If you want to make the motor reach high speed rotation, the pulse frequency should be accelerated, that is, the lower the starting frequency, and then at a certain accelerationto the desired high frequency (motor speed from low to high speed). Stepping motor with its significant features in the digital manufacturing era plays a major use. With the development of different digital technologies and the advancement of stepping motor technology, stepper motors will be applied in more fields.
