Automotive Parts Testing

Cars are exposed to harsh environments, which will lead to performance issues and failure, reducing the car's lifespan. The quality of the car's parts directly affects the car's overall quality. So, when new products are being developed and produced, many parts need to undergo strict environmental simulation tests to ensure they are of good quality. These tests usually include high and low temperatures, and high humidity conditions.

These tests check how well parts of cars work in different conditions. The most common motors and mechanical transmission parts used are stepper motors, servo motors, electric cylinders, linear modules and planetary reducers. These parts are usually tested in environments between -40 and +85°C, but they usually only work in temperatures between 0 and 40°C. In these environments, ordinary stepper or servo motors and mechanical transmission components face the following challenges:

At low temperatures, the grease in the motor or mechanical transmission components will become thicker, even solidifying and freezing, which can make it hard to start the motor. Low temperatures will also cause the insulation to crack, and condensation and frost can form inside the motor, causing internal short circuits and damage to the motor. Low temperatures also reduce the mechanical strength of the motor and mechanical transmission components, making them brittle and reducing their load-bearing capacity. 

High temperatures will deform the internal materials of the motor and mechanical transmission parts, and the plastic parts become soft and fail. High temperatures can also demagnetise the motor's magnetic materials, reducing the output torque, or cause the insulation material to fail, triggering a short circuit. High temperatures can also cause the grease to fail.

Kingsni specially developed motors and mechanical transmission products can solve seemingly unsolvable problems in the series when it comes to high and low temperature environments. Kingsni motors and mechanical transmission parts use special materials, designs and lubrication technologies to work well over a long time at temperatures ranging from -40 to +85°C or wider. This means they can solve the problems that ordinary products have when working at high and low temperatures.
Kingsni motors and mechanical transmission products are widely used in automative parts testing applications such as door, lock, handle, horn, electric seat, rear-view mirror, instrument panel button and display touch testing.
