Abstract

The present invention provides a motor control device that can reduce costs by reducing metal plates. In addition, the motor control device described above has high vibration resistance, can be easily assembled, and has a small installation area when mounted on a control panel. The motor control device has: a main circuit board on which a semiconductor is installed; a case on which the main circuit board is built; and a heat sink contacting with the semiconductor to dissipate heat generated from the semiconductor. through-hole on the side panel and is located on the outside side of the control panel.

Description

technical field [0001] The invention relates to a motor control device. Background technique [0002] A motor control device for driving a spindle synchronous motor has a main circuit substrate, a control substrate, a dynamic braking resistor, an anti-shock resistor and a box. Large components such as fuses and electrolytic capacitors that smooth the converter output are mounted on the main circuit board. [0003] Circuit components such as CPU and ICs for controlling the inverter are mounted on the control board. The box body has: a metal plate supporting the main circuit substrate, a control substrate, a dynamic braking resistor and an anti-shock resistor; and a heat sink cooling the semiconductor elements of the converter and the inverter. [0004] Such motor controls are mounted on a control panel contained in the equipment. The control panel has a box shape. The motor controls are mounted on the back inside the control panel. When the heat generated by the motor co...
