POWERTEC Brushless DC Motors

POWERTEC's selection of enclosures - TENV, TEAO, DPFG and DPBV - provides suitable motor enclosures and mounting for virtually any industrial environment. The motors are available with NEMA foot mountings; NEMA C-face, and D-flange mountings are also available.These brushless DC motors use efficient ceramic ferrite permanent magnets bonded to the rotor to produce the magnetic field. Thus, there are no losses in the motor due to rotor induction currents. All of the current delivered to the brushless DC motor is used to develop torque.The powerful and lightweight permanent magnet rotor design provides low rotor inertia for high torque to inertia ratios in a relatively small frame. This high torque density equates to a very responsive motor with high starting and running torque, rapid start-stop capabilities and smooth operation over the entire speed range.The brushless DC motor is a true synchronous motor. The rotor field is always in sync with the excitation field; it does not have losses due to slip. This factor, inherent to brushless DC design, combined with various primary and secondary feedback options, allows for precise speed and torque control.Reliable, low-maintenance brushless DC motors do not have any brushes to replace or a commutator to wear out. Little heat is generated in the rotor allowing the bearings to run cooler while increasing bearing life. Factory mounted feedback devices are integral to the motor and eliminate high maintenance couplings.
