Stepper motors

Stepper motors are the perfect solution whenever high accuracy of the geometrical position of the system driven by this motor is required. Stepper motors can be found in many devices and machines. Good examples of wide range of usage of stepper motors are electromechanical clocks, inkjet and laser printers, 3D printers, many types of electronics, CNC machines.

Stepper motors are also installed in cars and motorcycles, which are driven by internal combustion engines. Then these elements perform the function of stabilizing the revolutions of the engine driving the vehicle at idle speed. The high holding torque gives the user the ability to precisely rotate the stepper motor shaft by the specified number of steps. The last parameter depends on the step resolution of the motor, but the use of an encoder is not required.

Due to their simple design, the stepper motors are reliable and easy to operate. Choose now stepper motors in Botland, which will prove themselves in many of your automatic and robotic projects. See the full list of products below!

How do stepper motors work?

The stepper motor's operating mechanism is relatively simple. The stepper motor is a brushless motor powered by pulse voltage. The stepper motor shaft does not rotate continuously as is the case with most types of electric motors. Shaft revolutions are discrete and its individual steps correspond to revolutions by the same number of angular degrees. Stepper motor with a resolution of 200 steps (1 full revolution of the shaft), a single step corresponds to a rotation of 1.80 °. The stator of the stepper motor consists of grouped windings to which voltage pulses are successively applied. A single voltage impulse applied to the winding from the control system causes the rotor to turn one step.

As we pointed out earlier, stepper motors have many uses. One of them is the use of this type of device for Arduino or Raspberry Pi programmable electronics. By connecting the stepper motor to Arduino through the motor controller, you can programmatically set such motor operating parameters as rotational speed, acceleration or the angular position of the rotor!

How to choose a stepper motor right? Technical parameters

A stepper motor is an electric motor that is characterized by a pulsed electric current supply. It is this property of the motor that makes its rotor not rotate continuously, but always performs a motion with a predetermined angle of rotation. When choosing a stepper motor, it is imperative to consider a number of specialized technical factors.

The first most important criterion for selecting an engine is its required sequence of the most frequently performed movements in terms of quantity in time and angle of rotation. The time required to reach the specified motor shaft position and acceleration and deceleration between zero and maximum rpm is critical. Therefore, for the proper and safe functioning of the structure, the stepper motor should also be selected in terms of parameters such as step resolution, motor torque, acceleration torque and shaft loads.

Additionally, take into account the geometrical dimensions of the engine when choosing. Pay attention to such technical parameters as the spacing of the mounting holes. Unlike unipolar motors, bipolar motors have each winding equipped with a middle tapping, so the torque can be higher. Usually stepper motors work in open-loop feedback systems. For applications where increased confidence is required, stepper motors operate in a closed-loop feedback loop that uses a sensor to keep track of the motor shaft position.

Stepper motors for various projects
