Traditional DC Brush Type – Vibration Motors

Pros:
  – Low cost
  – No driver IC required
  – DC drive signal

Cons:
  – Motor life not suitable for some applications
  – Not best choice for haptic feedback applications due to slow rise / fall times

Linear Vibration Motor – Coin Type 

Pros:
  – No Brush / Friction or  Shaft for better reliability and long life time
        LRA  ~  1,000,000 cycles
        Brush Type  ~  100,000 cycles
        ( 2 Sec ON / 1 Sec OFF )
  – Fast rise / fall times for Haptics
  – May be driven at very low voltage / current levels to optimize power consumption

Cons:
  – Higher cost than brush type coin vibration motors
  – Haptic Driver IC required
