ThinGap’s brushless DC, ring motor architecture allows for creative solutions for Optical designs by allowing critical parts of the system, such as lenses, to be integrated into the center of the motor. Our standard motors have IDs from 25mm to 200mm and custom motors can be made larger. Our “True-Zero ™”zero-cogging torque motors, coupled a high resolution encoder and precision bearings, offers a level of smoothness and precision not previously obtainable. This integrated design reduces parts count, weight, and ultimately cost.
