Title:
MOTOR CONTROL MODULE
Document Type and Number:
Japanese Patent JP3806381
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor control module, capable of accurately measuring the temperature of all electrolytic capacitors and FETs mounted on a board at low cost, for preventing degradation.
SOLUTION: A motor control module (1) constitutes an inverter circuit and controls a motor. It comprises a plurality of electrolytic capacitors (3) mounted on a board (10), a first temperature-detecting element which is bonded near the electrolytic capacitor (3) on the board (10) and measures the temperature of the electrolytic capacitor (3), a plurality of FETs (4), mounted to correspond to the plurality of electrolytic capacitors (3) on the board (10), and a second temperature-detecting element which is bonded near the FET (4) on the board (10) and measures the temperature of the FET(4). One terminal of the electrolytic capacitor (3) is connected to the first temperature-detecting element, while one terminal of the FET(4) is connected to the second temperature detecting element.
