Hysteresis Dynamometer


FIG 16


Overview
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.
