The eccentric rotating mass (ERM) motor and linear resonant actuator (LRA) are two of the most common types of haptic motors used in the market today. Vibratory motors incorporate haptic feedback into devices, like phones, smart watches, tablets, and other consumer electronics. Each motor has its own specification but can be customized to meet different requirements for larger volumes. They are used in applications with low power requirements. These motors provide the most effective haptic effects as a mode for communication for human interaction.
