Matched motion. Intelligent control.
From conventional DC drives to networked smart motors, Han Yale supplies window lift motors specified to the vehicle’s original control architecture—mechanical fit, electrical interface and signal behavior defined per part number.

Problem we solve
The connector is only the beginning.
Matching the connector alone is not enough. Across LIN Bus, dual Hall, ripple-count and conventional 2-pin designs, we verify the electrical interface, feedback characteristics and control response against the applicable original-equipment reference. In-house PCB, sensing-circuit and firmware development on automotive-grade ICs gives us greater control over calibration and component sourcing.
Electrical match
Voltage, connector, pin assignment and direction of rotation, following the original motor.
Control compatibility
The feedback or communication system the vehicle expects, including any vehicle-specific initialization procedure.
One product family / Four architectures
Matched to the original system.
Each architecture serves a different control arrangement. Motors are assigned by original-equipment reference and application, not by connector appearance alone.
01 / Networked control
LIN Bus Smart Motors
Integrated motor electronics exchange commands and diagnostic information with the vehicle’s control system.
- LIN 2.x smart node configurations
- Integrated transceiver and controller
- Application-specific protocol and diagnostics
- Smart window functions on specified variants
02 / Sensor feedback
Dual Hall Sensor Motors
Hall sensing provides pulse feedback for the vehicle’s window control architecture.
- Dual-channel Hall feedback for position and direction
- Pulse characteristics specified per application
- Power and dedicated sensor connections
- Signal timing and pin assignment per part number
03 / Sensorless feedback
Ripple-Count Motors
Motor commutation produces a current signature that the vehicle’s door module can use for tracking window travel.
- Position feedback through current ripple
- No separate Hall sensor signal wiring
- Commutation characteristics specified to the original-equipment reference
- Ripple signature and gearing must match
04 / Conventional drive
Standard 2-Pin DC Motors
Conventional window lift drives for applications requiring a standard DC motor.
- Two-pin power interface
- 12V or 24V variants by application
- Matched rotation polarity and connector
- Output and gear specified per part number
Functions and voltage options vary by part number. A two-pin connector does not establish ripple-count compatibility.
Choosing the right motor technology
Compare the control interfaces.
Where position is sensed, where the logic sits and what has to match the original. Final specifications are defined per part number.
| Interface | LIN Bus Smart Node | Dual Hall Sensor | Ripple Count | Standard 2-Pin DC |
|---|---|---|---|---|
| Position feedback | Hall sensing + on-board controller | Two Hall ICs on a magnet ring | Current ripple from commutation | None (switch-controlled travel) |
| Where the logic sits | Inside the motor, commanded over LIN | Door module / BCM reads Hall pulses | Vehicle door module counts ripples | Door switch / relay |
| Typical wiring | Power, ground + LIN line | Power + Hall signal lines | 2-pin power only | 2-pin power only |
| What must match the original | LIN protocol & diagnostics | Pulse count & sensor timing | Ripple signature & gear ratio | Voltage, polarity & mechanical output |
| Han Yale edge | Protocol decoded on the real vehicle | In-house Hall-sensing circuit, application-specific tuning | Commutation tuned & real-vehicle validated | Connector, rotation & output matched to the original |
Motor technologyNEW LINE
Ripple-Count Motors
Position sensing without a sensor. Each time the brushes cross a commutator segment, motor current dips and recovers. The door module counts these ripples to track the glass, with no Hall IC and no magnet ring, over the same two power wires.
- 2-wire, sensorless: fewer parts and pins, fewer potential failure points in a wet door environment.
- One signal, two jobs: the same current trace gives glass position and the load rise that triggers anti-pinch reversal.
- Where it's used: vehicles whose door module handles one-touch and anti-pinch directly, with applications in recent VAG and BYD models, as well as the latest Ford F-150 models.
Why generic replacements failThe door module is calibrated to the original motor's ripple signature. A different commutator segment count, gear ratio or noisy commutation can cause miscounts: the glass stops short, auto-up drops out, or anti-pinch reverses for no reason.

How Han Yale builds it
Waveform & signature matching
Commutation ripple is benchmarked against the vehicle's original signature. Where it deviates, alternative motors are sourced and validated until it matches.
Clean, stable ripple
Ripple amplitude is verified across temperature and voltage, to support reliable pulse detection by the door module.
Validated on the real door module
Full-travel count, one-touch up/down, anti-pinch reversal and reinitialization are checked on the actual vehicle, the same way we verify LIN nodes.
Direct-fit, plug & play
Original 2-pin connector and mounting. No wire-splicing or harness modification for a fast, straightforward installation.
Why the electronics matter
Built around system behavior, not just the housing.
Our engineering team reviews feedback type, signal behavior, mechanical output, operating noise and EMI so each motor behaves like the original in the vehicle.
In-house sensing-circuit design
Common sourcing challenge: off-the-shelf sensor modules may limit control over signal tuning and firmware. Tolerance variation or drift can contribute to false anti-pinch reversal.
Han Yale: designs the Hall-sensing circuit and PCB around automotive-grade Hall ICs and writes the firmware, tuned to our own regulator travel. In-house circuit design reduces dependence on third-party sensor modules and gives us greater control over component sourcing.
Real-vehicle validated protocol
Common sourcing challenge: bench recordings or physical motor matching alone may not capture vehicle-specific LIN behavior or ripple-count requirements.
Han Yale: verifies BCM and door-module behavior on the actual vehicle, to check compatible operation with the original vehicle system and identify communication-related diagnostic trouble codes.
Built on Taiwan's electronics ecosystem
Common sourcing challenge: outsourced PCB assemblies require defined calibration, ESD controls and firmware ownership to maintain consistent quality.
Han Yale: taps Taiwan's electronics supply chain, from automotive-grade Hall and motor-control ICs to qualified SMT partners, while firmware and calibration remain under Han Yale’s own control.
Before you source
Motor & smart control questions.
Does every motor support one-touch and anti-pinch?
No. These functions depend on the motor configuration and vehicle control system, and are defined per part number rather than across the range.
Can a standard two-pin motor replace a ripple-count motor?
Matching pin count alone is insufficient. A ripple-count application requires compatible commutation characteristics and gearing. Each reference is assigned the correct architecture during our cross-reference review.
Are motors available separately or with the regulator?
Both. Motors can be supplied on their own, or together with the regulator as a complete regulator-with-motor assembly. Regulators without motor are also available for original-motor reuse.
Do you support new developments?
Yes. References not yet in our range can be reviewed for development. Samples or drawings of the original motor help us confirm the configuration.
Is initialization required after replacement?
Some applications require initialization or relearning after replacement, following the vehicle’s service procedure. Not every replacement is calibration-free.
