Problems solved by technology
[0003] The original equipment is inconvenient to install the motor at the designated position, which is more troublesome to use, and a lot of vibration will be generated during the use of the motor, resulting in loose connection, affecting the test effect, and it is impossible to fix the messy wiring harness. The extra parts cannot be stored and are prone to entanglement, and more parts need to be used in the test process, which is easy to make the desktop messy and affect the use

The invention belongs to the technical field of urban rail traction alternating current motors, and particularly relates to a test device for an urban rail traction alternating current motor, which comprises a main body, the upper end of the main body is provided with a motor capable of being conveniently assembled and disassembled, and the lower end of the motor is provided with a bracket for supporting the motor. After the motor is placed at the upper end of the main body, the sliding seat is moved to adjust the distance, the pressing plate is rotated to be attached to the protruding part at the lower end of the support, at the moment, the main body can be fixed through cooperation of the bolts and the positioning holes, operation is easy, motors of different models can be conveniently fixed, and different data tests can be conveniently carried out; after the base is fixed to the upper end of the main body, the top plate is connected to the lower end of the supporting plate in a clamped mode, the clamping plate is further connected to the interior of the upper end of the top plate in a sliding mode, and the limiting plate and the two ends of the top plate are fixedly connected through bolts. And the test effect is prevented from being affected by connection looseness caused by overlarge vibration.
Description
technical field [0001] The invention belongs to the technical field of urban rail traction AC motors, and in particular relates to a test device for urban rail traction AC motors. Background technique [0002] With the development of power electronics technology, the electric traction AC drive system has gradually replaced the early DC traction drive system, and has been widely used in the field of rail transit, becoming the only choice and main development direction for railways to achieve high-speed and heavy-duty transportation. In the process of perfection, continuous testing is required, so a test device for urban rail traction AC motors has appeared on the market. [0003] The original equipment is inconvenient to install the motor in the designated position, which is more troublesome to use, and a large amount of vibration will be generated during the use of the motor, which will cause the connection to loosen, which will affect the test effect, and it is impossible t...
