Features

• 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 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 dependant 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 realised as the speed is proportional to the frequency of the input pulses.
