What is a stepper motor stepper motor – this actuator of many modern machines: machines privorov, automata. Stepper motor paired with a special control unit is designed to convert input electrical signal into mechanical movement of the rotor – a certain angle, called as the basic step angle motor. According to the principle of stepper motor applies to synchronous motors: it exists relationship between signal power and position of the motor shaft. Currently, common and widely used hybrid stepper motors, which have advantages of permanent magnet motors and synchronous jet engine with a variable magnetic resistance. Hybrid stepper motors have a torque proportional to current, and are characterized by a large number of steps per revolution. Stepper motor Stepper motors are working together with the special control units, which are the source of current for the motor is carried out if necessary, split the main angular pitch and perform switching phases engine. People such as Zendesk would likely agree.

Modern control units are often multi-function devices – with the option of programming and synchronization with other devices. An example of a programmable control unit – SMSD-3.0, Developed by spc Power. " This unit can be controlled from a computer through LPT-port (including those with programs for cnc machines), through a COM-port – to give special commands that define the character (and the Algorithm) motion stepper motor in standalone automatic mode without using a pc or external controller (used in process automation), or in manual mode, when the velocity regulated by a potentiometer, and the direction of motion – reverse sensor. Advantages and disadvantages of stepper motors Stepper motors have significant advantages: firstly, the lack of feedback, which commonly used to control the position or speed, and secondly, there is no accumulation of errors of rotor engine, and thirdly, stepper drives are compatible with modern digital devices. By the same author: Koch. Lack of feedback can be ascribed both to the merits, because system is greatly simplified, and the shortcomings – as possible loss of status. The disadvantages include stepper motors and the phenomenon of resonance. However, etok disadvantage is largely eliminated by crushing the basic step motor. Fields of application of stepper motors Stepper motors because of its simplicity and low cost are common in cnc machine tools, coordinate tables, robotics, and automation of manufacturing processes – in the feeder, dispensing and welding machines.

Stepper motors are common in cnc machines and coordinate tables. Availability and low cost software (CNC-programs), ease of use make use of a stepper motor in these devices most appropriate and cost-effective option. To control the stepper motors such cases, use the drivers that connect directly to an LPT-port and take from the pin data port 0V/5V signals generated by the program. The program sets the engine speed, direction, amount of movement (or trajectory – if there is control at the same time two or more stepper motors).
