1.Brief Introduction of 0.9° stepper motor

• 0.9° step angle means 400 steps in one rotation, because 0.9° x 400=360°, 0.9° stepper motor is more precise.
• When selecting a stepper motor, pay attention to the rated voltage and current parameters.
• 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.
• 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 0.9 degree 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.
