| Abstract: | An experiment of temperature characteristics of ultrasonic motors is done in this paper.The result is used to analyze the factors of temperature rise of ultrasonic motors.The relation between pre-pressure,friction layer and temperature rise of ultrasonic motors and the relation between pre-pressure,friction layer,rotational speed and stall torque of ultrasonic motors was studied.The empirical formula for estimating the relation between the temperature rise and the rotational speed and stall torqueis proposed.These analyses provide a reliable theoretical basis for the lessening of heat generation of ultrasonic motors and improving the operation characteristics of ultrasonic motors. |
