Electric Power Dynamometer

Product Features

The motor is controlled by a frequency converter, with a maximum rotational speed of up to 50,000 rpm. The control performance is excellent, allowing for constant speed, constant torque, or constant power control.

The system supports four-quadrant operation mode, which can be used as a generator (load) or a power machine (driver). It can provide a certain load from zero speed to the maximum speed. Load characteristics: from zero speed to the rated speed, it is constant torque; from the rated speed to the maximum speed, it is constant power. Maintenance-free, energy-saving and environmentally friendly.

It is suitable for testing the characteristic curves of various motors, as well as temperature rise and simulation life tests. It is particularly suitable for testing the motor performance of main drive motors in new energy vehicles, automotive core components, permanent magnet synchronous motors, asynchronous motors, and joint motors.

Product Overview

The electric dynamometer is based on the principle of electromagnetic induction and dynamic control technology, constructing a precise load regulation system to achieve continuous load adjustment over the entire range and real-time collection of all operating conditions' parameters. It responds within milliseconds to core data such as voltage, current, and torque. For high-speed and high-power scenarios, it accurately simulates extreme states such as heavy-load start-stop and complex operation of industrial equipment, providing a comprehensive testing solution. The equipment features intelligent flexible load switching, high-precision data collection, and safe and stable operation. It covers a wide range from micro to megawatt-level motors. It is widely applied in sub-sectors such as rail transit power systems, ship power propulsion, renewable energy power generation equipment, intelligent equipment manufacturing, and precision transmission devices. It deeply integrates into the entire process of motor design and development, testing and certification, and mass production and application, providing professional technical support for optimizing the power performance and reliability verification of high-end equipment.
