Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, specifically to an electromagnetic compatibility testing platform for vehicle-mounted refrigeration inverter motors. Background Technology

[0002] A variable frequency motor is a motor that, under standard environmental conditions, operates continuously at 100% rated load within a speed range of 10% to 100% of the rated speed without exceeding the motor's rated allowable temperature rise.

[0003] With the rapid development of society and economy, electromagnetic compatibility (EMC) refers to the ability of equipment or system to operate in its electromagnetic environment in accordance with requirements without causing unacceptable electromagnetic interference to any equipment in the environment. Therefore, EMC includes two aspects: on the one hand, the electromagnetic interference generated by the equipment to the environment during normal operation must not exceed a certain limit; on the other hand, the appliance must have a certain degree of immunity to electromagnetic interference present in the environment, i.e., electromagnetic susceptibility.

[0004] The authorized publication number "CN221686512U" describes "an electromagnetic compatibility testing platform for new energy motors, including a base. An adjustment structure is provided on the inner side of the base. The adjustment structure includes a fixed plate fixedly connected to the inner side of the base. A first servo motor is fixedly connected to the bottom of the fixed plate. A transmission rod is fixedly connected to the output shaft of the first servo motor. A first transmission wheel is fixedly connected to the outer side of the transmission rod. A first transmission belt is drivenly connected to the outer surface of the first transmission wheel. A first driven wheel is drivenly connected to the left end of the first transmission belt. A second transmission wheel is fixedly connected to the outer side of the transmission rod. A second transmission belt is drivenly connected to the outer surface of the second transmission wheel. This electromagnetic compatibility testing platform for new energy motors allows for the adjustment of the testing height and direction through the adjustment structure, thereby collecting electromagnetic signals from different angles and positions, resulting in more comprehensive test data."

[0005] The aforementioned patent adjusts the height and direction of the test by adjusting the structure, thereby collecting electromagnetic signals from different angles and positions, thus making the test data more comprehensive. However, it cannot be displayed at an angle during use to facilitate the use of staff. Utility Model Content
