AC electric dynamometer is one of the load dynamometer equipment, especially in the load dynamometer test of power machinery, it can take into account the low speed and high speed load dynamometer test of each power machinery. It is particularly significant in the load dynamometer of low-speed machinery. It can provide the rated torque of the electric dynamometer almost from zero speed. The electric dynamometer can be used as the reverse drive prime mover of power machinery, as well as the power of mechanical efficiency test and engine starting power.
Features of AC electric dynamometer:
◆ Energy saving: convert the mechanical energy generated by the prime mover into electrical energy and feed it back to the internal power grid for use by other equipment.
◆ Loading mode: provide two-way consistent loading capacity, which can still provide sufficient loading capacity when the speed reaches 0r/min; The load characteristic is constant torque characteristic from zero speed to rated speed, and constant power characteristic from rated speed to maximum speed.
◆ Transient load characteristics: the main time of load response of electric dynamometer is ms level.
◆ Anti-dragging capability: the electric dynamometer can be easily converted into the motor driving mode, absorb energy from the power grid, and serve as the power machinery reverse drag prime mover.
◆ Good reliability and long service life: adopt mature and reliable technology, select famous brands at home and abroad, minimize the probability of product failure, and extend the service life of the product.
◆ Emergency protection features: provide multiple protection functions such as phase loss, overvoltage, overcurrent, overspeed, etc. to protect the dynamometer and test products in case of failure.
◆ Good maintainability: users can carry out daily maintenance (also when replacing the host and sensor) to reduce maintenance costs.
