Heavy Rumble Motor (Left)

Tests low-frequency heavy rumble weight motor typically used for explosions & impacts.

100%

Light Rumble Motor (Right)

Tests high-frequency light rumble motor used for subtle textures, gunshots & engine revs.

100%

Dual Motor Haptic Sweep

Sweeps both motors simultaneously from 0% to 100% power over 2 seconds.

Haptic Motor Diagnostics

Both left and right grips should produce distinct vibration feedback. If one motor fails to pulse or produces a rattling sound, the internal eccentric weight offset may be loose or disconnected from the main PCB.

Understanding Controller Haptic Vibration Technology

Vibration feedback is essential for modern gaming immersion, providing tactile cues for weapon recoil, vehicle engine revs, and environmental feedback.

Types of Controller Haptic Actuators

  • ERM Motors (Eccentric Rotating Mass): Asymmetrical weights attached to small DC motors in the grips (found in Xbox Controllers and DualShock 4).
  • Linear Resonant Actuators (LRA): Voice-coil based haptic actuators providing wide-frequency haptics (found in Nintendo Switch HD Rumble & DualSense).

Frequently Asked Questions

Why does my controller not vibrate during the web test?

Web Gamepad API vibration is supported in Google Chrome, Microsoft Edge, and Opera on Windows and macOS. Ensure rumble is enabled in your system Bluetooth or OS device settings.

What is the difference between heavy and light rumble motors?

Most gamepads contain two distinct eccentric rotating mass (ERM) motors. The left grip houses a heavy weight motor for low-frequency impacts (explosions), while the right grip houses a light weight motor for high-frequency haptic cues (gunshots).

Can vibration testing damage my controller battery or motors?

No. The test triggers standard motor pulses identical to normal gameplay feedback.
