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

A device that converts electrical energy into mechanical motion or force to drive movement within an assembly.

Product Specifications

Technical details and manufacturing context for Motor/Actuator

Definition
A core component of the Movement Assembly that provides the mechanical force or motion required for system operation. Motors typically generate rotational motion, while actuators produce linear or rotary motion to position, move, or control mechanical elements.
Working Principle
Operates by converting electrical energy (in electric motors) or fluid pressure (in hydraulic/pneumatic actuators) into mechanical energy through electromagnetic induction, piezoelectric effects, or fluid dynamics to create motion.
Common Materials
Copper windings, Steel laminations, Aluminum housing, Permanent magnets
Technical Parameters
  • Power output, dimensions, and torque specifications (W/mm/Nm) Standard Spec
Components / BOM
  • Stator
    Stationary part that generates rotating magnetic field
    Material: Electrical steel laminations
  • Rotor
    Rotating part that converts magnetic force into mechanical rotation
    Material: Steel/Copper/Aluminum
  • Bearings
    Support rotor shaft and reduce friction during rotation
    Material: Steel/Ceramic
  • Housing
    Protects internal components and provides mounting structure
    Material: Aluminum/Steel
Engineering Reasoning
0.1-100 Nm torque, 100-6000 RPM speed, -40°C to 155°C ambient temperature
Insulation breakdown at 155°C winding temperature, permanent magnet demagnetization at 180°C Curie point, bearing seizure at 120°C lubricant degradation
Design Rationale: Joule heating exceeding Class H insulation rating (155°C), thermal expansion exceeding bearing clearance (0.02-0.05 mm), Lorentz force-induced mechanical stress exceeding yield strength (250-400 MPa for steel)
Risk Mitigation (FMEA)
Trigger PWM inverter switching at 20 kHz causing 1000 V/μs voltage transients
Mode: Partial discharge in winding insulation leading to dielectric breakdown
Strategy: Multilayer insulation with corona-resistant polyimide film (200 μm total), dv/dt filters with 100 ns rise time limitation
Trigger Radial load exceeding 1.5 kN at 6000 RPM causing Hertzian contact stress
Mode: Bearing raceway spalling with 0.1 mm depth material removal
Strategy: Ceramic hybrid bearings with Si3N4 balls (G10 grade), preload adjustment to 15 μm axial clearance
