If you are involved with high performance EV applications, there is an important motor technology which is pancake motor (or disc shaped motor) from GoldenMotor.
What separates the pancake motor from conventional axial motor is its slotless disc armature. This difference enables pancake motors to deliver a level of performance which is not attainable with conventional ironcore motor designs used by most traditional power wheelchairs in today's market.
In addition to performance advantages, pancake motors have a unique flat & compact shape that is best fit for motorized wheel applications, such as power wheelchairs, power scooters.
The unique advantages that the slotless pancake motor technology has brought include:
Very long operating life
Absolutely zero cogging for ultra smooth velocity & torque even at slow speeds
Low armature mass for high accelerations and decelerations
Low inductance for almost instantaneous torque
Very high peak torques for rapid accelerations
Flat motor profile for extremely compact size
Stamped winding technology for very high reliability and low cost
Low Electrical Noise
