Takano Torque Controller controls torque using the hysteresis loss induced by the relative rotational motion between the magnetic hysteresis disk and multi-pole magnetic disk constituting its body.
It maintains constant torque using the hysteresis loss induced by the relative rotational motion between a magnetic hysteresis disk and a multi-pole magnetic disk, regardless of the slip revolution speed and the rotational direction.2. Excellent repeatability
The scale on the housing allows stepless torque setting with high repeatability.3.Long life
No contact part leading to long-life.4.Easy to install
No wiring, no power supply required. Easy to use.

As shown by the drawing, a torque controller consists of an 8-pole-magnetized disk (1) and a hysteresis disk (2).
Each segment of the hysteresis disk (2) facing poles of the magnetic disk (1) is magnetized by magnetic induction to the opposite polarity. As the hysteresis disk (2) and the magnetic disk (1) rotate relatively to each other, the segments of the hysteresis disk (2) are alternately magnetized, causing hysteresis losses.
Hysteresis losses will become the resistance torque equivalent to the frictional force that prevents the hysteresis disk (2) from rotating. This resistance torque will increase with smaller gaps between the hysteresis disk (2) and the magnetic disk (1).
