    Mini 180g Cm 300g Cm Nema 8 Bipolar Stepper Motor 20mm 0.8A

    Hybrid Mini Stepper Motor Nema8 20mm Unipolar Step Motor 180g.cm 300g.cm

    A hybrid stepper motor has an axially magnetized rotor, meaning one end is magnetized as a north pole, and the other end a south pole. Toothed rotor cups are placed on each end of the magnet, and the cups are offset by half of a tooth pitch.

    6.Advantages of Hybrid Stepper Motor

    The advantages of the Hybrid Stepper Motor are as follows:-

    • Low cost for control achieved
    • High torque at startup and low speeds
    • Ruggedness
    • Simplicity of construction
    • Can operate in an open loop control system
    • Low maintenance
    • Less likely to stall or slip
    • Will work in any environment
    • Can be used in robotics in a wide scale.
    • High reliability
    • The rotation angle of the motor is proportional to the input pulse.
    • The motor has full torque at standstill (if the windings are energized)
    • Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3–5% of a step and this error is non-cumulative from one step to the next.
    • Excellent response to starting/stopping/reversing.
    • Very reliable since there are no contact brushes in the motor. Therefore, the life of the motor is simply dependent on the life of the bearing.
    • The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
    • It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
    • A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.
