Planetary Gear Reducer Electric Motor Dynamometer & Chassis Test Bench

Introduction

1. The traditional loading methods include eddy current dynamometer, hysteresis dynamometer, magnetic powder brake, etc. The low-speed performance of eddy current loading is not good, and even cannot be loaded at low speed; magnetic powder brakes cannot be used in high-speed applications, and hysteresis dynamometers cannot be used in high-power applications, and the above types of dynamometers need to be installed with a cooling water circulation system. The system does not need cooling auxiliary facilities, which brings great convenience to use.

2. Adopting a unique all-digital control device, the electric dynamometer has two operating states: electric and dynamometer, and can run in a four-quadrant state. It can be used as a generator or a motor; it can be loaded in the forward direction. It can also be loaded in reverse.

3. Fast dynamic response and good control characteristics.

4. Simple structure, good stability, reliability, convenient use and simple maintenance.

5. The stability of constant torque and constant speed control is unmatched by other loaders. It can maintain extremely high stability in the whole speed (even at zero speed) and torque range.

6. It can easily achieve zero torque and zero speed start, so as to complete the real impact-free soft start of the power grid and machinery.
