Abstract
This paper proposes a new magnetic plane motor capable of rotation by the resonance energy of double-cantilever beam model excited by an electromagnetic force. This magnetic plane motor has two double-cantilever models, and the rotational direction is able to change by changing of the vibration mode. Basic characteristics of a prototype for the magnetic plane motor, such as rotational speed, output torque and efficiency were determined experimentally. Experimental results demonstrated that the rotational speed of 8.1 rpm was obtained with output torque of 0.07 Ncm for the magnetic plane motor having double-cantilever model. The output torque characteristics of the magnetic plane motor with two double-cantilever models improved 200 percent compared with double-cantilever model.
Highlights
There is an increasing demand for a micro-motor able to rotate with high promotion torque for personal computer and OA devices
A number of studies have investigated the mechanisms of the motor using devices such as an electrostatic elements [1]-[5], an electrorheological fluid [6], a shape memory alloy [7] [8], a magnetostrictive element [9]-[11], and a new type [12] by combination of a frictional force and an electromagnetic force
We propose a new type of a magnetic plane motor which combined an electromagnetic force and a mechanical resonance
Summary
There is an increasing demand for a micro-motor able to rotate with high promotion torque for personal computer and OA devices. (2014) A New Type of a Magnetic Plane Motor Coupled Mechanical Vibration with Electromagnetic Force. The ultrasonic motor is used for an electric appliance and a robot widely because the control characteristics are superior This motor is very expensive a cycle of the use is short. We propose a new type of a magnetic plane motor which combined an electromagnetic force and a mechanical resonance. Double-cantilever beam model with a tip mass such as a permanent magnet was excited by using the electromagnetic force. Double-cantilever beam model performs resonance, and a resonance energy produces rotational torque. This motor has the characteristic of the low-speed and high output torque, and the structure is considerably simple. The motor with double-cantilever beam of multiple was fabricated, and the influence of each parameter on torque and efficiency property was considered
