As electric vehicle technology continues to advance, mid-drive motors, as an efficient and stable driving method, have been widely used in electric bicycles, electric motorcycles, robots, home appliances, and other fields. This article mainly explains the definition of the mid-drive motor, the mid-drive motor test solution, the purpose of the mid-drive motor test, and the content of the mid-drive motor test, to provide readers with a comprehensive understanding.

Ⅰ.Mid-Motor Definition

A mid-drive motor is a type of motor that is installed in the middle of a mechanical device. In the field of electric power-assisted bicycles, a mid-drive motor specifically refers to a design in which the drive motor is installed in the middle of the frame, that is, under the seat or at the pedal position, and the rear wheel is driven by a chain or belt drive.

Ⅱ.Mid-drive Motor Test Solution

AIP has developed a mid-drive motor test solution for mid-drive motors. Based on the motor structure, AIP currently has the following test solutions: motor stator tester, motor rotor tester, and motor tester.

Ⅲ.Mid-drive Test Purpose

The main purpose of the mid-drive motor test is to evaluate the performance, reliability, and durability of the motor and ensure that it can work stably under various working conditions. Specifically, the test objectives include:

① Performance verification: Measure the motor's power, efficiency, current, voltage, speed, torque, and other parameters. Through testing, it can be verified whether the motor meets the design requirements and how it performs in actual applications.

② Ensure the quality of the motor: Electrical performance testing is an important means to inspect the quality of the mid-drive motor.

③ Optimize motor design: Electrical performance testing can provide data support for the design optimization of the mid-drive motor.

④ Ensure equipment safety: As a core component of electric vehicles and industrial equipment, the safety of the mid-drive motor is of vital importance.

⑤ Meet regulatory and standard requirements: Many countries and regions have established standards and regulations for electrical performance testing of motors in electric vehicles and industrial equipment.

⑥ Improve user experience: Electrical performance testing can help improve user experience, help users better select and use motors, and improve the overall performance of the equipment and user satisfaction.

Ⅳ.Mid-drive motor test content

The electrical performance test contents of the mid-drive motor mainly include AC hi-pot, insulation resistance, surge, NTC resistance, inductance, rotation, winding resistance, no-load, loading, Hall, back electromotive force, etc.
