Technical details and manufacturing context for Stator Assembly

Definition
The stator assembly is the stationary part of an actuator motor that contains the windings or permanent magnets. When electrical current flows through the windings, it creates a magnetic field that interacts with the rotor's magnetic field to produce torque and rotational motion. In actuator motors, the stator assembly provides precise control over the motor's position, speed, and torque output.
Working Principle
The stator assembly operates by converting electrical energy into a rotating magnetic field. When alternating current is applied to the stator windings, it creates a magnetic field that rotates at a specific frequency. This rotating magnetic field induces currents in the rotor (or interacts with permanent magnets on the rotor), creating electromagnetic forces that cause the rotor to turn. The stator's design determines the motor's speed, torque characteristics, and efficiency.

Frequently Asked Questions

What materials are used in your stator assemblies?

Our stator assemblies use electrical steel laminations for the core, copper windings for conductivity, insulation materials for safety, and a structural steel frame for durability.

How do I specify the insulation class for a stator assembly?

The insulation class (e.g., Class F, Class H) indicates the thermal tolerance of the insulation materials. Specify based on your motor's operating temperature requirements and industry standards.

What factors determine the number of poles in a stator assembly?

The number of poles determines the motor's synchronous speed and is selected based on the desired RPM and power supply frequency (e.g., 2-pole for 3600 RPM at 60Hz).

Can I contact factories directly on CNFX?
