Wireless Dynamometer

Introduction

The wireless dynamometer, also known as a dynamometer, is mainly used to test the power of the engine, and can also be used as a loading device for gearboxes, reducers, and gearboxes to test their transmission power. Mainly divided into hydraulic dynamometer, eddy current dynamometer, and electric dynamometer.

Electric dynamometers use electric motors to measure the torque output on various power mechanical shafts and combine the rotational speed to determine the power of the device. Because the power machinery being measured may have different rotational speeds, the motor used as an electric dynamometer must be a motor that can be smoothly adjusted in speed. The most commonly used are DC dynamometers, AC dynamometers, and eddy current dynamometers.

Specification

Working principle

When the wireless dynamometer is working, the controller provides the excitation current to the hysteresis dynamometer. When the internal coil of the hysteresis dynamometer is energized, magnetic lines of force are generated, and a closed magnetic field is formed through the stator tooth pole, air gap, and rotor hysteresis cup. Because the magnetic lines of force are densely distributed in the salient pole part of the teeth, and the distribution between the teeth is relatively thin, when the rotor rotates, the hysteresis cup induces a potential and generates an eddy current, and the eddy current interacts with the magnetic field to generate torque, which is the load. moment. The magnitude of this torque is only related to the magnitude of the current applied by the controller to the dynamometer coil, and has nothing to do with the speed at which the motor under test drives the dynamometer to rotate. The main difference between the dynamometers is also the principle, and the specific performance is also different.

Advantages

1. The power dynamometer test system adopts DJC AC variable frequency feedback loading, and the loading energy is fed back to the power grid through the AC load generator;

2. The torque and speed are directly measured by the torque sensor;

3. The electricity comprehensive measuring instrument detects current, voltage, frequency, power factor, etc.; the computer automatically detects, displays, and completes data processing, reports and various curves.

4. Superior low-speed loading capacity, and can achieve high-speed loading;

5. High-speed torque response speed (ms level);

6. It can be used as a motor to provide anti-drag capability;

7. Good reliability, long service life, convenient and simple maintenance;

8. The basic construction is simple, self-air cooling, and no external cooling system is required;

Applications

The wireless dynamometer has a wide range of applications, and the inspection products include hydraulic motor, engine, motor, reducer, gearbox, transmission mechanism, electric push rod, etc. It can be said that as long as the product can move (it can also move if it rotates), the dynamometer can be used for testing (the dynamometer can also be used for testing the product that cannot move, but generally most the sensors are directly used for testing without a dynamometer). Similar to the dynamometer is the test system, which adds parameter tests such as electrical parameters, hydraulic parameters, etc. to the dynamometer
