Higher Power Density ThinGap motors lead the industry in power density, i.e. power (watts) / weight or volume ratio, allowing higher performance with a smaller motor. The electromotive coil design is lighter than conventional coils. The design of the coil allows high copper packing density and eliminates the need for slotted laminations. In turn, this eliminates eddy current and hysteresis losses caused by laminations. A solid steel ring fixed to the rotating magnet structure replaces the stationary slotted laminations. The eddy current losses in the coil are very low and easily controlled. This configuration increases motor efficiency, enabling higher shaft torque and horsepower. |
