Introduction

Electric dynamometer is a test instrument used to measure various characteristics of power machinery. This machine is suitable for the performance test of large, medium and small power motors, internal combustion engines, gas turbines, hydraulic turbines, engineering machinery, forestry, mining, oil drilling and other machinery, and can also be used as a power absorption device for other power equipment.

Working principle

(1) A device that uses motors to measure the torque output on various power mechanical shafts, and combines the speed to determine the power. Because the power machinery to be measured may have different speeds, the motor used as an electric dynamometer must be a motor that can smoothly adjust the speed. Power dynamometers are divided into DC power dynamometers and AC power dynamometers. At present, AC power dynamometers are more commonly used .

(2) The DC feedback loader is an advanced loading device that uses a DC generator as a load and feeds the generated electric energy to the input terminal through its loading and feedback controller (inverter). It is connected with a torque sensor, namely Compose a DC power dynamometer with excellent performance.

(3) The AC variable frequency electric feedback loader uses an AC variable frequency motor as the load motor, and regulates the load and performs energy feedback through a special vector engineering variable frequency device. It is matched with a torque sensor to form an AC power dynamometer with excellent performance.
