Insulated electricity power :600VAC/1mA/1sĬopy the example code below into an Arduino program.A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.It is possible to achieve very low speed synchronous rotation with a load that is directly coupled to the shaft.The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.Therefore the life of the motor is simply dependant on the life of the bearing. Very reliable since there are no contact brushes in the motor.Excellent response to starting/stopping/reversing.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.The motor has full torque at standstill(if the windings are energized).The rotation angle of the motor is proportional to the input pulse.Your position is known simply by keeping track of the input step pulses. This type of control eliminates the need for expensive sensing and feedback devices such as Open loop control means no feedback information about position is Number of input pulses applied.One of the most significant advantages of a stepper motor is its ability to beĪccurately controlled in an open loop system. The frequency of the input pulses and the length of rotation is directly related to the The speed of the motor shafts rotation is directly related to The sequence of the applied pulses is directly related to the direction of The motors rotation has several direct relationships to these applied The shaft or spindle of a stepper motor rotates inĭiscrete step increments when electrical command pulses are applied to it in the A stepper motor is an electromechanical device which converts electrical pulses intoĭiscrete mechanical movements.
