Electric motor maker Linear Labs plans to start mass-producing its new high-torque M200 e-mobility motor for off-the-shelf use in September 2020, targeting a goal of delivering at least 100,000 M200 motors by the end of 2021.

The motors use a magnetic tunnel to surround the stator, resulting in  twice the torque of competitor motors.

Source: Linear LabsThe M200 motor and controller are based on the Hunstable Electric Turbine, an exterior permanent magnet circumferential flux four-rotor machine. These motors use a magnetic tunnel to surround the stator, resulting in twice the torque of competitor motors, or the same torque in half the size. The units can be manufactured with rare-earth or ferrite magnets and offer extended battery life and the performance needed to propel e-bikes and e-scooters up steeper inclines for longer periods of time.

Four of the torque-dense motors installed in a four-wheeled vehicle can deliver more peak torque than a 2020 Porsche 911 Carrera S engine. This is achieved by a smaller distributed electric powertrain with a combined quad-motor volume of just over 4 L. The M200 is also the first open drip-proof motor with an integrated controller able to work underwater for marine applications. The motor/controller combination has greater efficiency across the full speed range and is ideal for variable speed applications.
