DW series eddy current dynamometer

Case Presentation

DW/DWD series eddy current dynamometer - product background

Summary:

Eddy current dynamometer is the current domestic advanced loading dynamometer equipment, especially in small and medium-sized power and small power machinery loading dynamometer tests, the mechanical power of low speed and high load dynamometer test aspect, relative to other type dynamometer load equipment, in the performance, price, reliability, maintenance, degree of difficulty has obvious advantages. Especially in the low speed machinery and small power machinery load dynamometer, it is other methods are incomparable.

DW/DWD series eddy current dynamometer is specially designed for the output characteristics of small and medium-sized internal combustion engines. It has the characteristics of simple structure, small moment of inertia, high tolerance speed, long service life, easy maintenance, easy control and operation, wide measuring area, small swing resistance and good repeatability, and is very suitable for various small and medium-sized internal combustion engines and their components, variable speed converter and other dynamic performance and testing under different working conditions.

In general, the main measuring accuracy of various dynamometers and their measuring controllers is as follows:

1. Torque measurement accuracy: ±0.4%F.s, sensitivity ≤0.1%F.s

2. Rotational speed measurement accuracy: 0.1%±1r/min

The torque measurement accuracy of each series of dynamometers can be increased to ±0.2% F.S. if specially required by the user. At the same time, the eddy current dynamometer can be derived from the starting and running-in device or the frictional work measuring series. And can also according to user demand, provide a variety of power and transmission machinery complete test system.

The eddy current dynamometer is mainly composed of eddy current brake and various measuring and controlling instruments (including loading control, force measurement and speed measurement). Each part of the company has its own system, so that you can very easily form the required test system. Whether you buy a new complete system or upgrade existing equipment, it is a good choice for you.

The main features

Simple structure, easy operation and maintenance;

High braking torque, high test accuracy, stable operation;

The rotational inertia is small and the dynamic response speed is fast.

Matching with the measurement and control system, automatic operation can be realized.
