Product Description

High-speed AC power dynamometer is a new type of power loading test equipment

Features and advantages of high-speed AC electric dynamometer:
AC electric dynamometer is a new type of power loading test equipment based on four-quadrant AC asynchronous motor speed and torque control technology, which can realize the localization of all components of power loading/driving test equipment, and is an advanced power loading/driving mode!
The AC power dynamometer equipment independently developed and designed by Changniu Technology has a power supply voltage from 220V to 6000v, a power from 3KW to 6000kw, a single machine torque of 50000Nm, a single machine speed of 15000r/min, and a stable speed of 0.01r/min.

Technical characteristics of high-speed AC power dynamometer:
Changniu Technology's ultra-high-speed, low-inertia and high-dynamic AC power dynamometer equipment has the following characteristics:
1. A variety of operation modes, according to the needs of the equipment, continuous work, interval work, variable speed work, forward and reverse operation, fixed-point positioning, rapid braking, soft start and soft stop and other modes
2. It can be used as both loading equipment and prime mover, and can be driven and suction power in both rotation directions, and it is convenient to center during installation (flange connection and motor suspension can be realized)
3. Stand-alone torque range: 0-50000Nm; Stand-alone speed range: 0-15000 r/min;
4. Power range: 3kW-6000kW; Power supply voltage: 220V-6000V; Rated frequency: 16.7Hz, 25Hz, 33.3Hz, 50Hz, 66.7Hz, 75Hz, 100Hz, 125Hz, 133.3Hz, 150Hz, 175Hz, 200Hz, 250Hz, etc
5. Measurement accuracy: rotational speed±1 r/min; Torque ± 0.1% FS
6. Control accuracy: speed±1 r/min; Torque ± 0.2% FS
7. Loading stability: constant torque loading stability is better than 0.2%, constant speed drive is better than 0.1%
8. Overload capacity: 150% over-torque≥ 10min, 200% over-torque≥1 min
9. The single machine has a wide torque range (0-50000N.m), and it can be fully loaded at zero speed, and the speed can be reduced to zero without torque attenuation, and it can reach 2 times the full load in a short time.
10. Excellent loading performance: from zero speed to rated speed, it can maintain constant torque loading, and maintain constant power loading above the rated speed.
11. Low moment of inertia and high overload capacity make the dynamometer have high dynamic response speed, dynamic response speed: <5ms
12. Frequency conversion control mode: DTC direct torque control
13. Interference to the power grid: energy closed-loop control, harmonic voltage less than 2%, harmonic current less than 4.5%, energy recovery grid meets European CE standards
14. Low wear (self-dependent dynamic and static hybrid bearings have lifelong lubrication), maintenance amount, and the system is basically maintenance-free.
Excellent performance of electric dynamometer:
The electric dynamometer has the function of driving and reversing in the constant speed mode.
The electric dynamometer has the function of dynamometer loading in constant torque mode.
In the dynamometer loading state, the energy emitted by the electric dynamometer can be fed back to the grid directly or dissipated by the chopper brake resistor
Electric dynamometers do not require a cooling water system:
The motor under test ----------- torque transducer -------- electric dynamometer
The engine -------------- torque sensor -------- electric dynamometer
Drive motors----------- reducers--------- torque sensors---------- electric dynamometers
Drive motor----------- reducer--------- accompany the test reducer---------- torque sensor---------- electric dynamometer
