The application of DC Motor for industry machinery is very mature, and it has been for a long time. Although AC Motor with AC Inverter has replaced DC Motor for some general applications like lower / normal torque, velocity control without precision position, the applications which concern about high torque at low speed, high efficient in high power, precision control in speed, tension..etc, these still need DC Motor; Euntay Electric has produced DC Motor Drive (Analog Type)
since from 1988, we keep on concentrating our attentions on its application, we co-work and grew up with our clients, therefore, we setup the experience and technology, and these are our core competency in the market of DC Motor Control and Drive.
Now, we have developed our second generation Digital type of DC Motor Drive, V65D DIGITAL DC MOTOR DRIVE, The output rated armature current range is from 35A to 720A. which are applied to 2Q & 4Q control for the DC Motor based on power(H.P) 10 H.P ~ 200 H.p / 200VDC, 20 H.P ~ 400 H.P / 400VDC.
Microprocessor-control circuits.
Self-diagnostic function.

RS-485 Interface and MODBUS communication protocol.

 Two and four-quadrant control models.

Armature voltage, AC & DC tacho or encoder feedback.

Phase sequence (R-S-T) detection and automatic adjustment function.

No need to do frequency adjustment.
Flux-weakening control function.

Magnetic-loss protection function.

Electronic type motor-overload protection function.
