ThinGap’s proprietary electromotive coil technology improves brushless motor performance by eliminating the need for wire-wound stators with slotted laminations. Instead, precision machined copper sheets create a stand alone copper coil with structure, replacing the slotted laminations and copper magnet wire used in conventional motors. This allows higher copper packing density and a higher ratio of copper to total coil volume, providing very high power/torque density efficient electric motors. Cogging torques that accompany traditional motors are completely eliminated due to the absence of magnetic materials in the stator, and torque ripple effects are significantly reduced due to our unique coil design. This results in an extremely smooth and powerful motor with ample design flexibility.
The thin stator profile allows for previously unattainable motor design flexibility. ThinGap's motors provide an open-frame design platform, allowing easy fabrication of custom hubs and shafts for superior integration into the mechanism. The center of the motor is essentially hollow, allowing mechanism components to be located inside the motor. Due to the thin stator profile rotors can have magnets mounted outside the inner iron of the rotor, inside the outer iron of the rotor, or both. ThinGap motors are highly customizable - we offer a variety of rotor/stator combinations that achieve a range of torque/speed characteristics.
ThinGap’s unique motor design provides excellent:
Mechanical Flexibility due to an open-frame design and through hole, giving engineers opportunities to achieve a high level of integration into their applications.
Power / Torque Density due to a higher copper packing density and a higher ratio of copper to total coil volume. Very low ripple torque (<0.045%), low eddy current losses, excellent cooling, and the absence of cogging and coil hysteresis losses provide unsurpassed power and torque density.
Smoothness due to the absence of cogging, very low ripple torque (<0.045%), low eddy current losses, no lamination ringing, no radial forces between rotor and stator to cause wobble, and high inertial damping.
