  • Model 3 motor types

    May 20, 2018· Hey all - I got a chance to talk to a Tesla motor engineer the other day and asked him what type of motors the Model 3 is using To my surprise, he gave me a straight up answer He said the rear motor is not an induction motor, but one that uses permanent magnets (also known as a Brushless DC or "BLDC" motor) This surprised me, as I expected Tesla to stick to their induction motor roots.

  • Permanent Magnet

    Permanent-magnet stepper motors have alternate polarities of permanent magnets on the rotor surface, while the rotor iron, if it is used, has no teeth In one type of construction, the rotor has no iron, and the stator consists of two windings that set up alternate poles when energized, just as in the case of the hybrid motor.

  • Magnets (types)

    Magnets used for MRI are of three types: permanent, resistive and superconductive Permanent MRI magnets use permanently magnetized iron like a large bar magnet that has been twisted into a C-shape where the two poles are close together and parallel In the space between the poles the magnetic field is uniform enough for imaging.
