A stepper motor is an electric motor, powered by an electric current in the mode of pulsation. Currently used stepper motors with permanent magnets, hybrid engines and variable reluctance. They can be divided into bipolar and unipolar. Allow to obtain a high accuracy of motion.
A bipolar stepper motor, czteroprzewodowy. Has a threaded shaft that allows you to use the device as a linear actuator. Is supplied with the voltage of 12 V, consumes 0.4 A per coil. The time kept of 2.03 kg*cm (0,20 Nm). Dimensions: 39 x 39 x 34 mm.
A bipolar stepper motor, czteroprzewodowy. It has a resolution of 400 steps per revolution (0.9 degrees). It feeds a voltage of 3 V, consumes a current of 1.7 A per coil. The time kept is 4,89 kgf*cm (0,48 Nm). Dimensions: 42 x 42 x 48 mm - NEMA 17.
Stepper motor equipped with an impeller that performs the rotational movement of the fixed angle. This means that the rotation angle depends on the amount of the supplied current pulses, in turn, the frequency equal to the frequency of the pulse, which is multiplied by the value of the angle of rotation of the rotor in one cycle. Stepper motors are mainly used in mechanical devices regulation, in measuring devices, DVD drives and CD printers like inkjet, dot matrix and plotters. Used in addition in the field of robotics, check motion control of a robot arm. In turn, automobiles are responsible for engine idle speed.
A stepper motor has no brushes, which increases its reliability. Service life depends on the quality of the bearings. Characterized by repeatable movements and accurate positioning. Contributes to the rapid braking, changing direction and rozbiegowi. Its design allows precise control without feedback that does not require feedback. This leads to savings, as there is no need to use additional feedback devices.
The advantages of a stepper motor may also include the ability to achieve low-speed synchronous rpm , as well as a wide range of operating speeds, which we get due to the proportionality of the speed to the frequency of the input pulses. Botland offers stepper motors with a variety of options.
Models are available with a large and a small nominal voltage, different frequency, dimensions, weights. We offer bipolar stepper motors and unipolar.
