Working principle of stepper motor


To make the motor shaft turn, first one electromagnet is given power, which makes the gear’s teeth magnetically attracted to the electromagnet’s teeth. The point when the gear’s teeth are thus aligned to the first electromagnet, they are slightly offset from the next electromagnet. So when the next electromagnet is turned ON and the first is turned OFF, the gear rotates slightly to align with the next one and from there the process is repeated. Each of those slight rotations is called a step, with an integer number of steps making a full rotation. In that way, the motor can be turned by a precise. Stepper motor doesn’t rotate continuously, they rotate in steps. There are 4 coils with a 90o angle between each other fixed on the stator. The stepper motor connections are determined by the way the coils are interconnected. In a stepper motor, the coils are not connected. The motor has a 90o rotation step with the coils being energized in a cyclic order, determining the shaft rotation direction. The working of this motor is shown by operating the switch. The coils are activated in series in 1-sec intervals. The shaft rotates 90o each time the next coil is activated. Its low-speed torque will vary directly with current.


Custom Shaft & Mounting Details:


All motors can be supplied with single or double ended shaft to customer request shaft length and other dimensions can also be modified on demand.


Number of Leads:


All motors can be supplied with 4, 5, 6 or 8 leads and if required a connector can be provided on our motors to customer request


Winding code:


Since each customer request can be different, we list only our standard products in this catalogue. However, we will be happy to quote other variants to your request.


Holding Torque:


Holding torque is measured with two phases supplied at the rated current. The enclosed technical specifications are therefore typical.

(On customer request for special shaft, leads, fixings, etc. We will provide you with a unique product code/identifier)
