Effective Management

Posted by domain admin in News

The problem of effective management of a stepper motor for a long time did not allow the stepper motor a common practice in industrial equipment. In recent years, many leading manufacturers more seriously turned their attention to the stepper motors as an alternative replacement of the traditionally used asynchronous motors. Large role in this was that the market began to appear highly Driver to control the stepper motor. Some of these new, modern drivers to control a stepper motor is a stepper motor driver SM-18 and SM-19 designed and manufactured by Scientific-Production Enterprise “Dzherelo” Dnepropetrovsk, Ukraine. Model driver stepper motor SM-19 is designed to control a stepper motor in step mode. Stepper drive driver model SM-18 is designed to control stepper motor mode free running, ie, contactless mode of the DC motor (samorazgonny mode). The main technical characteristics of the models SM-18 and SM-19 are: – Three-wire control – power supply – constant or variable current – a range of supply voltages from 20 V to 40 V – Power consumption not more than 1.75 A (Model SM-19) nor more than 3 h (model SM-18) – starting torque by using the stepper motor DSHR-56 -1.8-1210 in the voltage range, at least 0.7 kg / cm (0.7 H / M). – Management is performed through an open collector circuit or logic level (logic zero from-12V to +0.6 V, the level of the logical unit from +4 to +12).

Performed both drivers on the basis of the microprocessor with once the internal programmable ROM. Microprocessor service: power supply, power reset, the block of emergency relief, the unit of analysis the currents of the windings, the unit of analysis of the rotor position. Key bridge amplifiers are controlled microprocessor. Circuit is made of 18 transistors and is available on the printed circuit board size 135 * 53 mm. No radiator, cooling the natural. To connect the external circuit driver of SM-18 and SM-19 are: 1. Connector for the voltage supply (2 pins) – AC, AC. 2.
