The invention provides a device for collecting motor parameters, and the device comprises a first synchronous pulley, a second synchronous pulley, an encoder and a fixed seat, wherein the first synchronous pulley is detachably connected to an extended end of a motor shaft, and the second synchronous pulley is connected to an encoder shaft. The first synchronous pulley is connected with the secondsynchronous pulley by a synchronous belt, and the fixed seat includes a front support and a rear support. The front support and the rear support are oppositely disposed, wherein the front support is provided with a front bearing, and the rear support is provided with a rear bearing. The outer sides of the front support and the rear support are respectively provided with a front end cover and a rear end cover. The encoder is connected to the front end cover, and an encoder shaft passes through the front bearing and the rear bearing. The second synchronous pulley is located between the front bearing and the rear bearing. The external encoder is used for the acquisition of the motor parameters, thereby improving the utilization rate of the motor. Moreover, there is no need to connect an encoder to each motor, thereby achieving the control over the cost of the motor. In addition, the encoder is accurate in measurement.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a device for collecting motor parameters. Background technique [0002] Traditional permanent magnet synchronous motors have two ways to control the motor. The first one is to drive the motor directly with a driver without an encoder, which is commonly known as "open loop". The second is to install an encoder at the end of the motor shaft, which is commonly known as "closed loop". The motor parameters are collected through the encoder, and then the motor is accurately driven through the driver. Among the above two structures, the first one is not equipped with an encoder, which cannot drive the motor accurately and affects the effective utilization of the motor. The second is to install the encoder at the end of the motor shaft, which improves the utilization rate of the motor, but also increases the cost of the motor. Contents of the invention [0003] In view of the deficien...
