    Tips: Velocity characteristic of stepper motor

    The rotational velocity of the stepper motor depends on pulse frequency, number of teeth and beats of rotor. Its angular velocity is in direct proportion to the pulse frequency. Meanwhile, the time synchronizes with the pulse. Therefore, under the circumstance that there is certain number of teeth and beats of teeth of rotor, the necessary velocity can be obtained by only controlling the pulse frequency. As the stepper motor is started by relying on its synchronic torque. To avoid step out, start frequency is not high. Especially, along with the increase in power, the diameter of the rotor increases and so does the inertia. The difference between start frequency and maximum operating frequency might be more than 10 times.
    To make full use of the rapid performance of motor, the motor is generally started at low frequency lower than the start frequency, and then the pulse frequency is increased gradually until the expected velocity is reached. To choose the change rate, it is necessary to ensure the step out doesn’t occur and acceleration time should be shortened as far as possible. To ensure the positioning accuracy of the motor, the velocity of the motor should be gradually reduced to the velocity (equal to or larger than the start velocity) at which the motor can stop from the maximum velocity.

    Strong Motor for an affordable price
    I love these motors. I currently have 4 of them and I have had them for about six months. They work great for what i was using them for and never seemed to have a problem. Just make sure you buy the right motor driver and power supply that will actually allow enough current through to power these motors.
    I recommend this motor to anybody that needs a strong motor for either a project or in need of some type of upgrade.
