Problems solved by technology

Since the mechanical connection between the motors is relatively complicated and high-precision coaxiality needs to be guaranteed, high technical requirements are put forward for the installers, otherwise, poor motor connections may cause severe vibration, motor beating, coupling A series of problems such as damage, motor damage, and speed feedback distortion
Therefore, the above-mentioned replacement / installation work is time-consuming, labor-intensive and there is a risk of damage to components
On the other hand, the replacement / installation operation will inevitably accelerate the wear and aging of mechanical connections such as couplings, thereby reducing the accuracy of the entire device and reducing the service life of the entire device

Embodiment Construction

[0028] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0029] figure 2 is a schematic diagram of the mechanical part of the motor loading device according to an embodiment of the present invention. As shown in the figure, the motor loading device 2 according to the embodiment of the present invention includes three motors 21 , 22 , 23 connected in series through a coupling 24 . It should be noted that the motor loading device of the present invention may include four, five or more motors, not limited to three as an example here. However, from the perspective of the complexity of the motor mechanical connection and electrical control, preferably, the motor loading device of the present invention includes three or four motors, so as to avoid causing the motor control system to be relatively complicated and / or difficult to ensure that the motors are connected at the same time. axis.

[0030]The three motors 21, 22, 2...

Abstract

The invention provides a motor loading device which is used in the performance test of a motor controller, wherein the motor loading device comprises at least three motors, output shafts of the at least motors are in series connection mechanically; in addition, any one of at least three motors is taken as a first motor which is connected with the motor controller the performance of which is tested and the first motor is taken as a control target of the motor controller the performance of which is tested. At least one of other motors of at least three motors is taken as a loading motor and the loading motor provides load for the first motor.

Description

technical field [0001] The invention relates to a motor loading device, in particular to a motor loading device used in performance testing of a motor controller. Background technique [0002] In the electrical industry, performance testing of motor controllers is often required. In the test, the motor controller is connected with the motor loading device, which provides the motor controller with motors under different loads, so that it is possible to simulate the control effect of the motor controller on the motor under different loads, and then realize the motor control The purpose of device performance testing. [0003] Traditionally, such as figure 1 As shown, the motor loading device 1 uses two motor-to-drag structures, and one of the motors 11 is connected with an external motor controller of the performance to be measured as its control target (for convenience of expression, hereafter, it is related to the performance of the test performance The motor connected to ...
