Description
Description Load Simulation Mechanism for Motor Technical Field The invention relates t a load simulation mechanism for a motor. Background of the Invention Nowadays, motors are used more and more widely, and mechanical equipment using motors as driving sources may be found everywhere. Various parameters of motors, such as rated power, rated current and service life, are major parameters for evaluation of a motor and also standards representing the performance of the motor. The performance of motors directly influences the related performances of various kinds of mechanical equipment driven by the motors. Therefore, measurement on various performance parameters of a motor also becomes very important. The operation situation of a motor under different loads is important information to be known. Summary of the Invention The purpose of the invention is to provide a load simulation mechanism for a motor, which can measure various parameters of a motor conveniently and has good universality. The technical purpose of the invention is mainly realized by the following technical solution: a load simulation mechanism for a motor is provided, comprising a soleplate, a motor supporting block is fixed on one end of the soleplate, and a load simulation device is fixed on the other end of the soleplate; the load simulation device comprises a support frame, the support frame is fixed on the soleplate and provided with a friction plate, a friction wheel which synchronously rotates along with an output shaft of a motor is disposed on one side of the support frame, and the friction wheel abuts against the friction plate; and the friction plate is connected with a hold-down 1 mechanism. After the motor is powered on, the motor drives the output shaft to rotate so as to drive the friction wheel to rotate as the output shaft is connected with the friction wheel. The friction wheel abuts against the friction plate, so that a friction force is generated between the friction plate and the friction wheel, that is, an external load is provided for the motor. The hold-down mechanism enables the friction wheel and the friction plate to be tightly connected to each other all the time, and meanwhile, the friction force between the friction plate and the friction wheel is adjusted by the hold-down mechanism. As the friction wheel rotates synchronously to the output shaft of the motor to be measured, the load on the friction wheel is changed, that is, the external load of the motor is changed. In this case, statistics on various performance parameters of the motor may be carried out according to demands of experimenter. The input voltage driving the motor is fixed, a current meter or a tachometer may be disposed on the external part of the simulation mechanism or a pressure gauge may be connected to the hold-down mechanism in accordance with different parameters to be measured. Different parameters of the motor under different load cases may be calculated conveniently by data on the meter, so the operation is simple and practicable. Moreover, the whole simulation mechanism has simple structure and low cost, and the used parts are standard parts which may be easily obtained by the user. The friction plate may be directly and movably connected onto the support frame, and may also be connected onto the support frame through other devices. Preferably, the friction plate is bonded to a friction plate fixing block.
