Head Restraints & Window BLDC Motor and Controller
How Headrest BLDC Works:
- Application microcontroller connected to the seat module power output or the vehicle power through the OEM specified connector.
- Interface to LIN as a slave.
- Optional interface to the seat switch
- Master BLDC motor
- Slave BLDC motor for two-way operations
- Motors spin a spindle
- Each spindle connects directly to the nut which moves the head restraint armature
- The motors are bolted to the frame of the head restraint.
Window Regulator Brushless Motor:
- Much better NVH performance – soft start and soft stop, insignificant inrush current, no mechanical stop noise at top or bottom, no relay clicking, and/or mechanical hard start/stop noise.
- Programmable Window Travel Speed – Constant speed, Express-Up & Down via Switch IF or via LIN command with bus voltage ranging from 9V to 16V.
- Meets anti-pinch maximum force requirements for unsupervised window moves – A “real” torque control enables better pinch force control.
- Vehicle Shipment Mode – Prevents the window from moving down due to long-term vibrations and meets the current requirement for sleep mode or quiescent current.
- LIN Diagnostics, Calibration, and Boot Strap Loader.
- FOC Torque control – Shortened time delay for anti-pinch activation and leads to a reduction in torque ripples.
- Speed is higher under the same torque (natural mechanical property).
- Capable of running at overloaded conditions.
- More Reliable – No brush dust or sparking and low EMI, without relay clicking with solid-state power bridge.
- Our data showed our WR brushless motors are quieter and lighter than existing brushed WR motors – 29.8% improvement in NVH and 23% lighter.
48V 3KW 4-Quadrant Motor Controller – 48V 3KW
24V EHPS — 24V
A 24V electric system assists the combustion engine while lowering current draw and improving fuel economy by 10% to 15% (3~5% fuel economy for EHPS only). Optimized integration of pump, motor, and controller improves overall efficiency, guarantees mounting compatibility, and implements a flexible control strategy.
