Dual Motor System: The Secret of Left-Heavy Right-Light

Why do controllers use two motors? How does this design simulate rich haptic feedback?

Left Motor (Low Frequency Heavy Rumble)

Typically uses ERM (Eccentric Rotating Mass). Slower rotation but stronger vibration, simulating explosions, collisions, engine roar and other low-frequency scenarios.

90% Intensity

Right Motor (High Frequency Light Rumble)

Modern controllers often use LRA (Linear Resonant Actuator). Fast response, simulating bullet impacts, button clicks, texture friction and other fine touches.

Future Technology

HD Rumble and Linear Motor Technology Evolution

Not all vibrations are the same. From traditional "buzzing" to precise haptics that can simulate ice cubes clinking - this is a quiet technological leap.

Nintendo Switch HD Rumble

Can simulate delicate sensations like "ice cubes clinking in a glass", even conveying object quantity and material information through vibration frequency.

DualSense Haptic Feedback

PS5 controller's Voice Coil linear motor, combined with adaptive triggers, can precisely recreate bow string tension, gun recoil, and different road surface textures.

Frequently Asked Questions

All about controller vibration

QWhy doesn't my controller support vibration?

Browser Gamepad API vibration requires HTTPS environment or localhost. If you're on an HTTP website or your browser is outdated, vibration won't work.

QDoes Switch Pro controller work?

Yes! Switch Pro controller's HD Rumble is recognized as standard dual motors in Web API. However, due to browser limitations, you won't experience true HD rumble effects.

QWill vibration damage my controller?

Normal use won't. Motors are designed for millions of cycles. Unless you vibrate at full intensity 24/7 for months (unrealistic), there's no need to worry.

QCan I customize vibration waveforms?

Web Gamepad API currently only supports simple dual motor control (intensity + duration). Complex waveform programming is only possible in native game engines (Unity, Unreal).

About Controller Vibration Feedback

Vibration (Rumble) is key to gaming immersion. Modern controllers typically use an "asymmetric dual-motor" design. This tool lets you independently control left and right motors to test vibration functionality.

Perfect for checking gamepad vibration test 3000 style diagnostics and troubleshooting weaker rumble issues on PC.

Asymmetric Motors Explained

  • Left Motor (Heavy/Low Freq): Larger internal weight, slower rotation. Produces heavy, intense low-frequency vibration (explosions, crashes).
  • Right Motor (Light/High Freq): Smaller internal weight, very fast rotation. Produces subtle, light high-frequency vibration (tire spin, gun recoil).

Why Isn't My Controller Vibrating?

  • 1. Browser Limitation: Please use Chrome, Edge or other Chromium-based browsers. Firefox has incomplete Gamepad API vibration support.
  • 2. Bluetooth Driver Issues: Windows native Bluetooth drivers have poor Xbox controller vibration support, may lose vibration or only have one-sided vibration. Try USB connection for testing.
  • 3. Low Battery: Some controllers automatically disable vibration motors in low-battery mode to save power.
