Technical Definition & Core Assembly

A canonical Galvanometer motor is characterized by the integration of Rotor and Stator. In industrial production environments, manufacturers listed on CNFX commonly emphasize Copper (coil windings) construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A specialized motor that precisely controls the angular position of a mirror in a galvanometer system.

Product Specifications

Technical details and manufacturing context for Galvanometer motor

Definition
The galvanometer motor is the core actuating component within a galvanometer mirror assembly, responsible for converting electrical signals into precise rotational movements to position the attached mirror with high accuracy and speed for applications like laser scanning, beam steering, and optical positioning.
Working Principle
Typically operates as a moving coil or moving magnet motor. An electrical current applied to the coil (or through interaction with a magnetic field) generates a torque proportional to the current, causing the rotor (and attached mirror) to rotate to a specific angular position defined by the input signal.
Common Materials
Copper (coil windings), Permanent magnet (e.g., Neodymium), Steel (stator/core)
Technical Parameters
  • Rotor diameter or mirror aperture size the motor is designed to drive. (mm) Customizable
Components / BOM
  • Rotor
    The rotating part that attaches to and drives the mirror; contains either the coil or permanent magnet.
    Material: Aluminum alloy or steel
  • Stator
    Stationary part containing the magnetic circuit (permanent magnets or coil) that interacts with the rotor to produce torque.
    Material: Steel laminations
  • Bearings
    Support the rotor shaft, allowing low-friction rotation and precise positioning.
    Material: Stainless steel or ceramic
