Product description
The vehicle motor test bench is a test system professionally developed by our company for the testing of the three-electric system of new energy vehicles, which can provide load simulation, motor and controller dynamic calibration, efficiency analysis, responsiveness testing, reliability testing, etc. for the output of new energy power system; The system synchronously measures the speed, torque, electrical parameters, temperature and other parameters of the motor under test. It can measure the relevant parameters of various types of motors for electric vehicles, permanent magnet synchronous motors, AC asynchronous motors and their supporting controllers, and complete M-S tests, dynamic response tests, speed and torque fluctuation tests, efficiency tests, temperature rise tests, stalled rotor tests, power feedback tests, etc.; Help users effectively evaluate the performance of the corresponding products.
SSCH300-4000/10000 electric dynamometer mainly consists of base, electric dynamometer, motor flange, torque sensor (torque flange and torque flange antenna), torque flange base, locking shaft support plate, lock sleeve, protective cover and locking shaft pins.
SSCH300-4000/10000 electric dynamometer is an indoor test system with high precision and high repeatability, whose main goal is to test the performance of new energy vehicle motor. Through the efficient control system, all test operations can be completed by computer control instructions. High speed data communication module makes the system have higher real-time performance. SSCH300-4000/10000 electric dynamometer has the characteristics of low speed, high torque and high dynamic response.
Its working principle is to invert the AC power from the electric dynamometer into DC power through the DTC inverter and then invert it into AC power for grid connection; DTC variable frequency inverter system adjusts the power grid current of the electric dynamometer to control the speed and torque of the prime mover. For example, when used together with the test and control system produced by Seelong, it can not only accurately measure and control the speed and torque of various rotating power machinery, but also can measure and control the temperature, pressure, flow, current, voltage, and other parameters.
SSCH300-4000/10000 electric dynamometer has two important features:
First, use the direct torque control technology to implement torque control on the AC dynamometer;
Second, when the AC dynamometer is in the power generation state, the electric energy is sent back to the grid.

SSCH300 electric dynamometer has the following significant advantages:
The basic principle of Hydraulic and eddy current dynamometer is to convert the mechanical energy generated by the prime mover into heat energy and take away the heat after cooling by water. The energy emitted by the prime mover cannot be recovered, and energy is also consumed during the conversion process. However, the electric dynamometer can convert the mechanical energy generated by the prime mover into electrical energy and feed it back to the internal grid for use by other equipment.
The loading characteristics of the electric dynamometers are constant torque characteristics from zero speed to rated speed, and constant power characteristics from rated speed to maximum speed, which fully comply with the load characteristics of power machinery. Generally, the hydraulic dynamometer can only be loaded in one direction, while an eddy current dynamometer can be loaded in two directions, it cannot be used as a power back-drag prime mover, while the electric dynamometer can easily realize two-way loading and can be used as a power back-drag prime mover.
Due to the use of accessories that fully comply with national standards, users do not have to rely on the manufacturer for maintenance, and can completely carry out daily maintenance by themselves, even when it is necessary to replace the host and sensors. The electric dynamometer is the most ideal replacement product for the technological transformation of enterprise testing equipment due to its simple structure and maintenance-free, in addition to its excellent speed control performance, it also has a significant energy-saving effect.
The electric dynamometer is the test core of the whole test bench system. It adopts the variable frequency inverter system as the actuator of the electric dynamometer and adopts Seelong’s new generation test and control system as the control core of the test bench system. Seelong software test system is developed based on C# platform and can carry out high dynamic control of the system. Seelong test and control system can automatically complete the relevant setting test cycle and user-defined dynamic test cycle; At the same time, Seelong test and control system can integrate external auxiliary equipment, perform centralized communication and control.
