Electric Vehicles (EVs)

EV platforms demand compact, efficient and long-life actuation solutions to support both drivetrain and auxiliary systems.

Our modular approach allows EV manufacturers to combine motors, gearboxes and feedback devices to meet precise torque, speed and control requirements.

  • High-efficiency auxiliary motion
    For cooling pumps, thermal valves, HVAC flaps, charge-port actuators and internal mechanisms.
  • Low-noise, low-vibration operation
    Essential in quiet electric cabins where mechanical noise is more noticeable.
  • Compact actuation
    For tight packaging environments within battery packs, dashboards and interior assemblies.
  • Durable, continuous-duty performance
    Suited to EV duty cycles and temperature extremes.

Power Steering Systems

Modern electric power steering relies on precise torque transfer and smooth, controlled assistance.

While primary EPS motors are large, Rotalink’s systems power secondary actuation, such as steering-column tilt, memory positioning and feedback mechanisms.

  • High-torque miniature gear motors
    Used in auxiliary steering actuation and steering-column adjustments.
  • Low-backlash gearing
    For responsive steering correction and stable operation.
  • Compact motor-gearbox assemblies
    Suitable for column, rack or drive-unit mounted systems.
  • Reliable performance
    Critical for steering safety, under vibration and shock.

Door and Window Mechanisms

Passenger-comfort and accessibility features rely heavily on small, efficient motion systems.

Our gearboxes provide the torque multiplication required for repeatable, safe movement in these high-cycle mechanisms.

  • Smooth, quiet window lift actuation
    Using compact geared DC motors.
  • Precise mirror adjustment
    (Tilt, fold, memory return) with miniature gear motors and encoders.
  • Reliable door locking/unlocking
    Through robust, small-form-factor gearmotor assemblies.
  • Controlled movement
    For sliding doors, tailgates and fuel flaps, where torque, safety and positional accuracy are essential.

Wiper Systems

Wiper actuators require controlled, torque-rich rotational output across varying speeds and duty cycles.

These systems ensure quiet, reliable operation consistent with automotive NVH (Noise, Vibration, Harshness) standards.

  • Stable low-speed
    High-torque output via worm or spur gearboxes.
  • Smooth, predictable wiper motion
    Including intermittent modes.
  • Durability under continuous load
    Moisture exposure and temperature change.
  • Compact, sealed designs
    Suitable for automotive exterior environments.

Why Gearboxes Are Important in Transportation Systems

  • Increase torque
    Allowing compact motors to deliver powerful, controlled motion.
  • Enable speed regulation
    Ensuring performance and safety across varying conditions. 
  • Improve energy efficiency
    Essential for electric and hybrid vehicle systems. 
  • Support precision control
    Critical for comfort, automation, and reliability.
  • Enhance system lifespan
    Through smooth, balanced torque delivery.
