Abstract

Lucid’s electric motors are optimized using a multi-physics and system level approach to deliver a compact powertrain that combines motor, gearbox, differential and thermal system into one cohesive package. Lucid’s powertrain sets multiple industry records with leading torque density of >20Nm/kg and power density of >15kW/kg while also delivering best in-class vehicle efficiency of up to 5miles/kWh. Miniaturization of the electric powertrain is key for creating spacious interior vehicle cabin and high efficiency has a compounding effect of reducing battery size and mass of the vehicle for the same range.
A power dense and ultra efficient motor presents unique challenges in electromagnetic design and thermal management. The presentation will cover examples of how Lucid uses 3D Finite Element Analysis tools to understand and overcome some of these challenges and extract the maximum performance out of the electric motor.
