HEV’s Stator Assembly for Electric Water Pumps (EWP) and Electric Oil Pumps (EOP) is a precision-engineered motor component designed to provide efficient, stable, and reliable electromagnetic performance in automotive thermal management systems. As the stationary core of the electric motor, the stator assembly generates the magnetic field required to rotate the rotor, enabling the pump to circulate coolant or oil efficiently. EWP systems are used for cooling engines, batteries, inverters, and other electric components, while EOP systems support lubrication and thermal management of motors, transmissions, and drive units.
HEV’s Stator Assembly is manufactured using high-quality electrical steel laminations, copper windings, insulation materials, and precision-engineered components. The laminated core is designed to minimize electromagnetic losses and support efficient motor operation, while optimized winding configurations provide stable torque and power characteristics. Depending on the application, the stator can be customized according to core dimensions, slot and pole configuration, winding specifications, wire diameter, insulation class, terminal structure, and other customer-specific requirements.
Precision manufacturing and systematic quality control are applied throughout the production process, including electrical steel stamping, lamination stacking, insulation processing, coil winding, terminal connection, resin treatment, and final electrical and dimensional inspection. Careful control of these processes helps ensure consistent electromagnetic performance, accurate dimensional tolerances, reliable insulation, and long-term durability.
The Stator Assembly is designed to support compact, low-noise, and high-efficiency electric pump systems. EOP applications commonly require efficient motors with low NVH characteristics, while automotive electric pump systems may operate across a range of vehicle voltage platforms and demanding thermal environments.
With its precision manufacturing capability and flexible customization, HEV’s Stator Assembly provides a dependable solution for automotive EWP and EOP manufacturers. It contributes to efficient fluid circulation, effective thermal management, stable motor operation, and improved system reliability. Suitable for hybrid, electric, and other advanced vehicle applications, HEV’s Stator Assembly supports the growing demand for compact, efficient, and durable electric pump technologies.
