At present in the advanced industrial countries, has a brush dc motor in the field of industrial automation has been gradually replaced by a brushless dc motor controller. Its application in the rising trend, what about the rest of the motor controller of governor, please read carefully. 1, the power supply voltage: 24 VDC, 36 VDC, 48 VDC, 220 vac. 2, brushless dc motor controller to control the drive: a closed-loop speed control. 3 rated current, low voltage driver: 5 a, 10, 15, a a. 4, high drive current rating: 1. 5,2。 5、4、5。 5, speed control range: 20 ~ 6000 RPM. 6, chopping frequency: 20 k. 7, the electric brake function, make motor controller quickly shut down. 8, overload ratio greater than or equal to 2. 9, positive and reverse control. 10, the PID speed and current double loop controller, when low speed can reach to maximum torque. 11, overvoltage, undervoltage, over current, over temperature, the hall signal, method of fault alarm and other functions. 12 and under the low speed torque can achieve maximum torque. 13, exquisite appearance size ease of installation. 14, all optical coupling clutch control signal. 15, suitable for all kinds of automation equipment, instruments, and other areas of the high speed. Brushless dc motor controller in the field of general industrial drive applications, regardless of the motor controller design or system design, improve the efficiency of saving energy should be in the governor important place.
