Study on Mechatronics Non-uniform Motion Production Device

Non uniform motion can be produced by using a servo motor to drive a middle transmission system. For a non uniform motion production in high speed and heavy load cases, a mechatronics , two degree of freedom mechanism is introduced in this paper. This mechanism is of two driving sources.The device not only has advantageous of constant speed motor for energy storing and releasing, but also has programmable ability of servo motor driving device and is optimally designed. Main power and torque are provided by constant speed motor and servo motor only modules output motion, that is, when servo motor motion is slightly changed, the output motion of this device will be changed so that various non uniform motions can be produced. A comparison of servo motor drive device, direct servo motor drive and the mechatronics device is carried out. The results indicate that only the mechatronics device can save both torque and power acted on servo motor which provides a good drive source for high speed and heavy load case.
