Design of USM Temperature Characteristic Measuring System

As temperature characteristic testing of ultrasonic motor needs, design a test system. The test system includes platinum resistance temperature sensor, temperature transmitter circuit, MSP430 microcontroller and PC. The test system use LabVIEW to develop software of the host computer. The host computer and the MSP30 microcontroller use serial communication （RS232 serial interface）. The test system can achieve real - time data acquisition of the motor temperature rise, high reliability and practicality. Carried out temperature rise test, for the ultrasonic motor using a certain type of aerospace equipment. The test proved that the ultrasonic motor under different ambient tem- perature ,the temperature rise of the basic stabilityof the operating temperature of - 30 ℃- 50 ℃ to meet the design requirements, to meet the particu larity of the space equipment.
