Eddy-Current Brake Dynamometers (WBSeries) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as...

“ MAGTROL offers 3 types of dynamometer brakes to absorb load: Hysteresis (HD Series), Eddy-Current (WB Series) and Magnetic Powder (PBSeries). Each type of Dynamometer has advantages and limitations and choosing the correct one will depend largely on the type of testing to be performed. With over 50 standard models to choose from, Magtrol Sales professionals are readily available to assist in selecting the proper Dynamometer to meet your testing needs. ”

Presentation

Magtrol’s WB23 and WB27 Eddy-Current Dynamometers are designed for very-high-speed motors and dental or surgical tool testing applications. By providing a braking torque that is proportional to the rotational speed, rated torque is reached at the rated speed.

The Dynamometers feature a low level of inertia, due to small rotor dimensions, and brake cooling is provided by air flow inside the dynamometer housing.

A PT temperature sensor continuously monitors the brake temperature and alarms the DSP7000 Controller to stop the brake excitation current in order to protect the dynamometer from overheating.

Torque is measured by a reaction torque transducer placed on the stator. The dynamometer has a torque measuring accuracy rating of ±0.2% full scale. The speed is measured by an optical sensor and a 2PPR (Pulses Per Revolution) encoder. This sensor measures speeds between 10000rpm and 100000rpm with a full scale accuracy of ±0.06% (using a DSP7000).
