Component Specifications

Definition
The stator/housing is the stationary outer structure of electric or hydraulic motors that serves as the primary containment and support element. In electric motors, it houses the stator windings and provides magnetic flux paths; in hydraulic motors, it contains the fluid chambers, ports, and internal mechanisms while withstanding hydraulic pressure. This component ensures structural integrity, thermal management, and precise alignment of internal parts.
Working Principle
In electric motors: Provides a stationary magnetic field through windings that interacts with the rotor's magnetic field to produce torque. In hydraulic motors: Contains pressurized fluid chambers that drive the rotor or pistons, converting hydraulic energy into mechanical rotation while maintaining seal integrity and pressure containment.
Materials
Electric: Laminated silicon steel sheets (0.35-0.65mm thickness) with copper/aluminum windings, cast iron or aluminum alloy housing. Hydraulic: High-strength aluminum alloys (e.g., 6061-T6), ductile iron (e.g., 65-45-12), or steel (e.g., 4140) with corrosion-resistant coatings. Both may include thermal management features and precision machined surfaces.

Frequently Asked Questions

What is the difference between electric motor stators and hydraulic motor housings?

Electric stators focus on electromagnetic properties and thermal management for windings, while hydraulic housings prioritize pressure containment, fluid dynamics, and corrosion resistance for hydraulic fluid systems.

Can stators/housings be repaired or must they be replaced?

Minor damage like surface corrosion or thread repair can often be addressed, but significant structural damage, cracks, or severe wear typically requires replacement due to critical tolerances and safety considerations.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
