摘要： An apparatus and method for servomotors of an electric injection molding machine includes a motion controlling unit, two driving amplifying units, and two servomotors respectively connected to the driving amplifying units. The motion controlling unit includes two servomotor position controllers both for receiving a first position command, and the driving amplifying units are respectively connected to the servomotor position controllers for receiving a second and third position command. Two position detectors are respectively received in the two screw caps that are mounted to the servomotors for detecting absolute positions of the corresponding screw caps. The screw caps are respectively connected to inputs of the first and second servomotor position controllers to form two screw cap position feedback circuits. The values of the screw cap position feedback circuits are compared to the first position command for being input into the driving amplifying units to drive the corresponding servomotors to act synchronously.

摘要： A voltage protecting apparatus is used for detecting voltage of a motor driver, and adjusting the voltage of the motor driver when at an over-voltage state. The motor driver includes a direct current (DC) power source and a power board. The voltage protecting apparatus includes a switch unit, a voltage transform unit, a controller, a voltage detector, and an over-voltage judger. When the controller outputs a high level signal, the switch unit is turned on, the voltage transform unit transforms the output voltage of the DC power source to a low voltage. The over-voltage judger receives the low voltage and compares the low voltage to a predetermined voltage. When the low voltage is greater than the predetermined voltage, the over-voltage judger outputs a control signal to the controller for signaling the controller to control the power board so as to adjust the voltage of the motor driver.

摘要： A system for driving a motor includes first and second rectifier circuits, a direct current (DC) link circuit, an inverter circuit, a voltage booster circuit, and a switch control circuit. When the motor is at a deceleration state, a micro control unit (MCU) outputs a first charging signal to turn on a switch of a first relay and turn off a switch of a second relay, a regenerative current from the motor is charged into a storage capacitor. Before the motor is in an acceleration state, the MCU outputs a second charging signal to turn on the switch of the second relay and turn off the switch of the first relay, and turn on a boosting switch, an increased voltage of the storage capacitor is charged into another storage capacitor. When a voltage at the DC link circuit reaches a predetermined value, the MCU controls the inverter circuit to accelerate the motor.
