All ThinGap Rotors are made up of outer and inner rotating irons to remove the necessity for magnetic attraction between the Rotor and Stator, dramatically increasing the smoothness of the motor. This Rotor design also allows designers wide latitude in attachments for power take-off; shafts of almost any design on one or both ends, weldments, screws, etc. can all be used.
All ThinGap Stators are constructed of etched copper sheets, laminated with insulating layers. This construction creates a rigid coil with a very high degree of consistency from motor to motor. Axial length, copper pattern and connections are used to create different torque and speed properties. There is no magnetic saturation, meaning that the torque limit is directly related to the ability to cool the motor.
The ThinGap Embedded Motor design provides exceptional cooling, allowing the motor to be driven hard at high currents result is a line of very smooth motors with very high power to weight ratios. In fact, on many models, continuous torque increases with rpm due to the cooling effect of the Rotor and the lack of iron in the Stator. Contact ThinGap for more details on this phenomenon.
