Discussion on Dynamometer and Motor Testing System

The structure of a dynamometer is very simple, consisting of a cabinet and a test bench. The test bench, also known as the dynamometer head, generally refers to a style where the torque and speed sensor and brake are integrated. The test bench includes a mounting base, torque and speed sensors, and mechanical loads (brakes); The cabinet includes electrical parameter testers, motor testers, dynamometer controllers, power supplies, etc. The functions of each component are as follows:

Installation base - used for the installation and fixation of the tested motor;

Torque speed sensor - used for collecting the speed and torque of the tested motor;

Mechanical load - generally using brakes, but also using motors, used to provide reverse rotational torque to the tested motor, absorb the power of the tested motor during operation, achieve "loading" of the tested motor, and simulate its actual operating conditions;

Electrical parameter tester - used for collecting and displaying electrical parameters such as voltage, current, and power of the tested motor;

Motor tester - used to collect the output signal of the torque and speed sensor and display the speed, torque, and mechanical power of the tested motor in digital form;

Dynamometer controller - used to control mechanical loads to output different torques;

Power supply - used for the power supply of the system and the tested motor.

For users, the dynamometer solves a more troublesome problem of loading and data collection, but the processing of test results still requires manual labor.
