The EC-i 52-mm brushless dc iron-wound internal rotor motor has been redesigned from seven pole pairs to eight pole pairs. This reduces the dc motor’s vibration and noise output. Available in three voltage outputs—18, 24 and 48 V—the 180-W motors produce up to 6,000 rpm. With a correspondingly optimized magnet ring, the motors offer a high torque density and a low cogging torque. The multi-pole internal rotor is dynamic and has a solid design with a welded stainless steel flange and housing.
