Temperature measurement technology using telemetry for electric motors.

マツイ東京本社

The high-density output of electric drive systems places the highest demands on rotor temperature measurement technology, whether on a test bench or during operation. This allows for the accurate and reliable acquisition of the motor's temperature profile under operating conditions, enabling the measurement data of rotor temperature to support development and design under all operating conditions. The telemetry signal amplifier from MANNER has a heat resistance of 200°C and high electromagnetic robustness. Additionally, its compact structure provides a high degree of design flexibility and allows for operation at high speeds of up to 30,000 rpm.
