DC motor driver

MMT-115/230RT10AL Product introduction product overview:

Mmt-115 / 230 DC motor governor is a full wave positive feedback DC motor driver, which can control the motor in two-way mode. Lifting arch four quadrant operation, so as to achieve forward and reverse torque in two speed directions; mainly applicable to products such as stacker welding machine, quenching equipment, automatic welding machine, etc.

Product features:

◇ suitable for permanent magnet motor and parallel excitation DC motor

◇ large torque at low speed starting state

◇ wide speed regulation rang

◇ it has a relatively hard mechanical property with a static error rate of 1%

◇ fast dynamic response process (adjustable) with automatic smooth transition during acceleration and deceleration

◇ positive and reverse soft start / soft stop time setting function (adjustable)

◇ enable locking control function

◇ forward rotation and reverse rotation are optional

◇ double closed-loop PI regulation (current and voltage), closed-loop feedback optional

Speed control mode and torque control mode can be selected

◇ inertia sliding stop and braking stop are optional

◇ input and output voltage can be selected for current setting and current limiting protection. (when the set current value is exceeded, the controller will automatically limit the output)
