Know knows very well the stepper motor, the motor is declines with the increase of rotational speed and torque, but also know the motor at low speeds can be normal operation, but after running speed higher than a certain value, it likely won't start. Because of stepping motor no-load start frequency the important technical parameters, refers to the motor under the condition of light pulse frequency can normal boot, if the pulse frequency is higher than the parameter value, the motor can't start properly, step or locked-rotor occur easily. Especially under the condition of the motor itself has a load, start frequency is lower, or start at high speed, normal operation of the motor. If must be of use to make the motor to achieve high-speed rotation, then in the pulse frequency should have a process to accelerate, not the beginning start when a high pulse frequency can be obtained directly. Specifically you take when starting motor with low frequency, wait until the motor normal boot after operation, then in a certain high frequency, acceleration to want to motor by the process of low speed to high speed, to meet the demand of motor high-speed rotation operation. So, everyone in the use of step motor, it is important to note that the ready to start operation, avoid high speed motor cannot be started this kind of phenomenon. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
