Haptic Motors

Haptic Motors

Johnson Electric Haptic Motors are Eccentric Rotating Mass (ERM) Motors that provide an effective way for designers to incorporate haptic feedback into their devices. ERM Motor platforms are available in both shaft and coin configurations. These configurations differ with respect to the plane in which the rotating mass spins. This difference defines their overall mounting and package sizes. ERM Motors create vibrations by utilizing a rotating eccentric weight. These haptic effects are customized by controlling the speed of the motor at start up, during operation and at braking.

ERM Motors are very suitable for applications which require a small, low power device. These motors; however, have an inherently high response time due to the need to spin the rotating mass up to speed and brake it back to zero. As a result, the "on" and "off" edges of the haptic effect are more rounded and less sharp as perceived to the end user. As such, these motors are very suitable for applications where simple haptic effects are the preferred mode of communication for the human-machine interface (HMI).
