    Nema 17 Stepper Motor Linear Actuator, 2 phase, 6V, 0.8A

    2 phase 6 wires, 0.8A 6V stepper linear actuator with a 1.8 degree Nema 17 stepper motor and a 152mm length precision lead screw, is ideal for applications requiring a combination of precise positioning, rapid motion and long life.
    SKU: ATO42H47-0806
    Delivery date: 6-12 days

    This Nema 17 Stepper Motor Linear Actuator can dramatically reduce cost and save space. Two versions can be delivered:
    1. Non-Captive shaft stepper linear actuator with nut inside motor. Linear moving part can rotate so it should be fixed.
    2. External shaft stepper linear actuator. Nut are mounted on lead screw.

    1. The stepper motor linear actuator is generally applied to the low speed situation with a speed of no more than 1000 rpm. It should work during this period through speed reducer. At this time, the work efficiency of the motor is high and the noise is at the low frequency state.
    2. Usually it is suggested that it is better not to use the whole step state of the stepper motor linear actuator because the vibration in the whole step state is large, and it is not suitable for long time operation and is easy to reduce the loss of service life.
    3. The motor with large seated number should be selected in load with large rotary inertia.
    4. When the motor is at a high speed or in a large inertia load, it usually does not start at the working speed but uses a gradual increase in speed and frequency. In a high precision state, a mechanical deceleration should be carried out to improve the speed of the motor, or a driver with high fine fraction should be used to solve the problem.
