Load testing system for high-speed motor

Abstract

The invention belongs to a motor testing system, and particularly discloses a load testing system for a high-speed motor. The load testing system comprises a dynamometer, a platform, a testing frame, a motor to be tested, a bearing seat, connecting shafts and high-speed bearings, wherein the platform is arranged on the testing frame; the dynamometer and the bearing seat are arranged on the platform; the high-speed bearings are arranged in the bearing seat; the dynamometer is connected with the motor to be tested through the connecting shafts; the middle parts of the connecting shafts are positioned in the high-speed bearings; the motor to be tested is fixed on the side wall of the bearing seat. The load testing system disclosed by the invention has the motor testing capacities under the conditions of rated power of 12 kW, rated torque of 20 Nm and maximum revolving speed of 30000 rpm, so that researching and testing capacities are greatly improved, the loading test requirement of the high-speed motor of which the rotational speed is as high as 12000 rpm is met, and the reliability of high-speed running of the testing system can be ensured.

Description

technical field [0001] The invention belongs to a motor test system, in particular to a high-speed motor load test system used in the fields of aerospace and electric power. Background technique [0002] With the further development of aerospace engineering, the reliability and performance requirements of the servo system supporting motors for aerospace models are constantly increasing, and the demand for high-speed motors is also increasing. [0003] However, the previous motor test system cannot meet the test requirements of 12000rpm high-speed motors, and there are problems such as unstable high-speed operation and low reliability. However, the maximum speed of most existing motor test benches is 11,000 rpm, which cannot complete high-power, high-speed motor tests, and cannot meet the test requirements of some types of high-speed motors. Contents of the invention [0004] The purpose of the present invention is to provide a high-speed motor load test system, which has ...
