Hysteresis Brake Dynamometer is designed for
testing with low to middle power appliances, especially
high-speed motor testing. It is able to provide a complete
measurement of a motor from free-running to rotor-locked because
the source of torque generated is not coming from speed. There
are three brake-cooling methods for our own designed hysteresis
brake dynamometers:
HD type: cooling by air fan or convection (no
external source)
AHD type: cooling by compressed air
BHD type: cooling by dedicated
blower
Our hysteresis dynamometers have achieved
accuracy ratings of ±1% full scale, depending on size and system
configuration. Fine adjustment for optimization can be done with
the support of our own invented dynamotmeter controller. It has
high cost/performance ratio with small size and simple operation
procedure. Customized or special designed of fixing units, based
on the customer requirement is possible.
