Recent in the study of ultrasonic motor using longitudinal and torsional modes were introduced. We analyzed the difficulties in the development of the motor,and pointed the direction of its research,in which the motor with high torque is very important one.
The development of the transfer mechanism of the two screw extruders was presented,the transfer mechanism was classified and analysed,the design and the key technology of the high torque type transfer mechanism of the two screw extruders were described.
Effects of friction and high torque on fatigue crack propagation in Mode III
To open and close the breech-block of a tank automatically, we used a switched reluctance motor (SRM) which has the characteristics of high speed, high torque, high efficiency, durability, and environmental robustness.
Planetary gears are widely used in aeronautic and industrial applications that require compactness and high torque-to-weight ratios.
Applications are limited at present because the currently available ultrasonic motors (USMs) do not provide sufficiently high torque and power.
