Industrial Harmonic Inline Gear Motors

Industrial Harmonic Inline Gear Motors


3MVz (3МВз) parallel shaft inline harmonic gear motors specifically designed for general industrial machinery. Harmonic (strain wave) gearing provides high accuracy positioning, high permissible/maximum torque and high resolution. Unlike conventional spur gears, the harmonic gear is capable of averaging the effects of tooth pitch errors and accumulated pitch errors to the rotational accuracy, thus achieving highly accurate, non-backlash performance.
