Thomson Lamination Company is a leading provider of motor lamination manufacturing services for high-performance electric motors. For the most efficient operation, these electric motors require parts built with precision construction and modern manufacturing processes. By understanding how the core electric motor parts work together, you can more confidently select manufacturing partners for your electric motor projects.
The four main parts of an electric motor are the stator, rotor, windings, and bearings.
Stator
A stator is the stationary component of a motor that forms a ring or exterior shell around the rotor. Stators are typically made of hundreds to thousands of motor laminations, or thin metal sheets bonded together. When properly energized, stators generate a magnetic field that rotates with the rotor. The stator’s materials, number of poles, and complexity of construction all determine the power of the field.
At Thomson Lamination Company, we manufacture high-quality motor laminations for stators. Each stator is made of thin layers of stamped metal that are stacked and bonded together in a specific configuration. The most common materials and grades we use include:
- Silicon steels for high conductivity
- M15
- M19
- Cobalt-iron alloys for high-efficiency and high-speed applications
- Hiperco 50
- Vacodur 49
- IMPHY AFK 502
- Nickel alloys for better magnetic fields at low power levels
- HyMu 80
- HiPerm 49
- VDM MAG 50
- VDM MAG 7940
- Permenorm 5000 V5
- ULTRAVAC 80
Rotor
A rotor is the rotating component of the motor that allows the magnetic field from the stator to rotate around a central point. The torque and spin of the motor is determined by the interaction between these two components.
Just like stators, most rotors benefit from a metal lamination-based design, though they can also be constructed from conductive metals embedded with magnets. At Thomson Lamination Company, our motor specialists produce precise rotor laminations using the same specialized materials as stator laminations. We also offer rotor and stator core stacking for optimal component alignment.
Windings
When energized, electric motor windings generate electromagnetic fields that rotate the rotor. For example, a three-phase motor will use windings in multiples of three to generate the fields and power the motor’s movement. At Thomson Lamination, we can produce custom laminations that optimize magnetic flux transfer and interact with your windings to minimize energy loss.
Bearings
Bearings are components that sit between surfaces that move relative to each other. Bearings minimize friction, enable smoother motion, and extend motor service life. Though we do not produce bearings, we configure our laminations so they have highly precise alignment with your bearings for maximum performance over time.
