This type of motor is used in GM's Chevrolet Bolt [1] and Volt, and the rear wheel drive of Tesla's Model 3. [2] Recent dual motor Tesla models use a combination of a permanent magnet motor at the back and traditional induction motor at the front.
Tesla makes two kinds of electric motors: an induction motor, and an internal permanent magnet (IPM) motor with synchronous reluctance motor (SynRM) characteristics. The older design is a three-phase four-pole alternating current induction motor (also called an asynchronous motor) with a copper rotor (which inspired the Tesla logo). [189]
Tesla stated that they use a platform approach to the powertrain components—using only a single permanent magnet motor rotor/stator design, a single induction motor rotor/stator design, a single motor inverter design, and a single gear set design—for all three configurations of Cybertruck—tri-motor all-wheel drive (AWD), dual-motor AWD ...
In December 2019, Tesla offered Long Range dual-motor Model 3 owners who had software version 2019.40.2 the option to purchase a US$2000 "Acceleration Boost" software upgrade enabling a Sport driving mode, [188] advertised to reduce 0-60 mph (97 km/h) time from 4.4s to 3.9s. Road testing confirmed better-than-expected acceleration with drivers ...
The most affordable Tesla available today is the Model 3 long-range rear-wheel-drive. This ride comes with Tesla’s single permanent-magnet-synchronous motor. The top speed is 125 mph.
The rotating magnetic field is the key principle in the operation of induction machines.The induction motor consists of a stator and rotor.In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current.
In one arrangement, the motor has an ordinary stator. A squirrel-cage rotor connected to the output shaft rotates within the stator at slightly less than the rotating field from the stator. Within the squirrel-cage rotor is a freely rotating permanent magnet rotor, which is locked in with rotating field from the stator.
Ferraris demonstrated a working model of his single-phase induction motor in 1885, and Tesla built his working two-phase induction motor in 1887 and demonstrated it at the American Institute of Electrical Engineers in 1888 [7] [8] [9] (although Tesla claimed that he conceived the rotating magnetic field in 1882).
