Stepper motor stepper motor is a kind of converts electrical pulses to angular displacement of the actuator. In general, when the stepper motor driver receives the pulse signal, it drives stepper motor in setting directions at a fixed point of view,The step Angle)Rotation. You can through the manipulation of the pulse number to control angular displacement, so as to complete the accurate positioning; At the same time, you can through the manipulation of the pulse frequency to control motor rotation speed and acceleration, so as to achieve the intention of the speed regulation. Stepper motor selection in electronic circuit converts dc power supply. Polyphase sequence to provide electricity for stepper motor control current. Only when the stepper motor power supply, the current step motor abilities normal operation. Usually, the step motor can not normal operation, able to use what way to distinguish whether or not it has been damaged. This article will share two practical methods, able to quickly and easily. First, it is necessary to understand the operation principle of stepping motor. Stepper motor selection in electronic circuit converts dc power supply. Polyphase sequence to provide electricity for stepper motor control current. Only when the stepper motor power supply, the current step motor abilities normal operation. If the stepper motor can not normal operation, identifying the damage way is as follows: first, under the condition of the equipment and wire lines don't pick up any, separate each line stepper motor, don't contact line, the rolling shaft with the hand, fine motor, should only need must strength, can rotate smoothly, there is no card phenomenon, if the card has somewhere or rolling, indicate the motor has been bad, may be the transfer of bearing, wear inside the rotor and stator. Traumatic force in the formation damage. Multimeter can be used to measure & other; Adjacent & throughout; Shall be equal to the product, the impedance of the coil impedance.
