Stepper motors

Stepper motors are an excellent solution for applications that require high position accuracy geometric layout with a drive through this engine. They can be found in particular in Electromechanical clocks, printers, inkjet and laser, printers, 3D, hardware, ELECTRONICS, CNC machines, automotive industry, for example, in cars and motorcycles equipped with internal combustion engine, performs the function of stabilizing the speed of the motor vehicle idling. High torque held entitles the user the exact rotation of the shaft of the stepper motor the specified number of steps depends on the resolution of the stepper motor without using an encoder. With its simple design stepper motors are reliable and easy to use.

How to operate the stepper motors?

A stepper motor is a brushless motor powered by a pulsed voltage, which the shaft does not rotate continuously, as in the case of most types of electric motors, but in an unobtrusive, where individual actions are in accordance with the rotation of the same number of degrees of rotation angle, for example, to a stepping motor with a resolution of 200 steps, which corresponds to one complete revolution of the shaft, one step corresponds to a rotation angle of 1.80 degrees. The stator of the stepper motor represent the grouped winding, which alternately serves voltage pulses. A single pulse voltage is supplied from the control system to the coil causes a rotation of the rotor one step. To connect stepper motor to Arduino driver (see also: drivers stepper motors), you can programmatically set the parameters for operating the engine as speed, acceleration or the angular position of the rotor.

What are the factors to consider when selecting a stepper motor for the project?

The first criterion for the choice of this engine is its necessary sequence often performed movements from the point of view of the amount of time and rotation angle. This is due to the time required to achieve a certain position of the motor shaft for acceleration and delay between the zero and maximum speed. In order for proper and safe functioning of the application engine should be selected to permit stepper, torque, time, acceleration and the load on the shaft. Should also take into account the geometric dimensions of the engine, the distance between the mounting holes, and two stepper motors of the same nominal supply voltage and sizes that are very close to each other, and may vary with the current consumption and the design of windings unlike motors unipolarnych bipolar motors have each winding is equipped with a medium back off that allows you to increase torque. Normally, stepper motors work in open loop. For applications that require high reliability, the stepper motors operate in a closed feedback loop that uses the sensor, so that you can track the position of the motor shaft.

Stepper motors - motors with a wide range of applications

On offer are Botland stepper motors, available in various sizes and options business days following the nominal supply voltage and torque, which allows for optimum matching of the engine under Your device. Because stepper motors require power supply a pulsed voltage, in practice, this allows for use in applications where accuracy is a priority. Because of this, these stepper motors are successfully running on machines with CNC and manual elektronarzędziach for precision materials processing, as well as in hard disks, clocks, printers, plotters two-dimensional, machine engraving, laser heads, equipment for scientific research, as well as the large-scale works - are also the ones supporting the production of integrated circuits and other electronic components. For applications that require high accuracy, we have also prepared a proposal of stepper motors with gearboxes extensions standard resolution stepper motors.
