0.9° Hybrid Stepper Motor Nema 23 Current 1A - 4.2A For Medical Equipment

motores paso a pas
1.Brief Introduction of 0.9° stepper motor

1. 0.9° step angle means 400 steps in one rotation, because 0.9° x 400=360°, 0.9° stepper motor is more precise.
2. When selecting a stepper motor, pay attention to the rated voltage and current parameters.
3. As long as the stepper motor drive power can control the current output, it is theoretically possible to use any supply voltage higher than the rated voltage of the motor.
4. If the drive power cannot control the current, you need to use a supply voltage close to the rated voltage, otherwise the motor will be at risk of overheating.

5.Advantages of Hybrid Stepper Motor

• 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.
