Precision HVAC and AC Motor Components for Automotive and EV Powertrain Applications

Aluminium Die Casting Rotor and motor flange for HVAC motor

In the rapidly evolving automotive sector, precision, performance, and energy efficiency are non-negotiable. Whether powering advanced EV powertrain systems or managing intelligent HVAC motor performance in smart vehicles, electric motors are central to the transition.

At Yuanzhong, we specialize in manufacturing high-performance AC motor stator and rotor laminations, serving critical applications from thermal systems to full electric drives. Our end-to-end in-house capabilities—spanning from stamping and tooling to aluminum die casting—allow us to deliver robust and optimized motor solutions for automotive needs.

Built for Efficiency: In-House Aluminum Die Casting for HVAC Rotors

For HVAC motors, rotor efficiency directly affects the overall energy performance of the system. At Yuanzhong, we offer in-house aluminum die casting for squirrel cage rotors, enabling:

• Better rotor balance and lower noise

• Improved electrical conductivity for reduced rotor loss

• Stronger mechanical bonding between laminations and rotor cage

• Consistent quality control from raw steel to finished rotors

This integration ensures higher efficiency and extended lifespan for HVAC motor applications, particularly in EV thermal systems and compact smart vehicle subsystems.

Key Applications in the Automotive Industry

1. EV Powertrain Manufacturers

Our rotor-stator assemblies support traction motors, e-compressors, and auxiliary drives. Optimized lamination thicknesses (0.2mm–0.35mm) and low core loss materials help boost performance.

2. Smart Vehicle Automation Developers

For window lifts, steering actuators, seat motors, and more, our compact motor cores are precision-stamped for high-speed and low-noise operation—ideal for automated platforms.

3. HVAC Motor Systems

With increasing demand for silent and efficient thermal control in electric vehicles, we provide custom HVAC stator and rotor laminations, paired with aluminum die-cast squirrel cage rotors, ensuring optimal airflow motor performance.
