Heat dissipators - Import export

Eddy-Current Brake Dynamometers (WB Series) 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 the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power, providing high continuous power ratings (max. 140 kW). The WB dynamometers have accuracy ratings of ± 0.3% to 0.5% full scale (± 2% for WB 2.7), depending on size and system configuration. Additional options include: high-speed version, speed pickup, mechanical rotor blocking device, OEM version IS and vertical mounting.

Pushing the boundaries of technology. The upper class of brushless DC motors. The high-power 4-pole motors provide maximum performance per unit of volume and weight, and make the buying decision easy with an unsurpassed service life. Ø 30 mm, 200 W. That is top performance. Thanks to the special winding technology and the 4-pole magnets, the maxon EC-4pole drives are unbeatable when it comes to delivering the highest driving power per unit of volume and weight. The motors have no cogging torque, high efficiency, and excellent control dynamics. The metal housing ensures good heat dissipation and mechanical stability. When it comes to service life, these motors also leave the competition far behind. Choose from three motor sizes: Ø 22, 30, 45 mm, short or long 90 – 300 WØ 22 – 32 mm, 90 – 480 W. 4-pole motors for maximum performance per unit of volume and weight guarantee a long service life.
