About Bühler Motor
Bühler Motor GmbH, headquartered in Nuremberg, develops and manufactures custom mechatronic drive systems for automotive, industrial and healthcare applications. The product portfolio includes DC motors up to 200 W, brushless BLDC motors up to 700 W, gear motors up to 10 Nm and electric pumps, including micro drives, encoders and brakes. The value chain ranges from development and in-house prototyping to the manufacture of stator-rotor assemblies made of electrical steel, plastic injection molding (including 2C/3C and hybrid parts) and die-cast components through to fully automated assembly. Production spans small quantities through to series production with around 17 million units per year. The independent, family-owned GmbH employs around 1,050 people worldwide, including more than 200 development engineers, and generates annual revenue of more than €270 million. With eight locations on three continents — including the Czech Republic, USA, Mexico, China and Japan — Bühler Motor supplies customers such as General Motors (Supplier of the Year 2025) and more than 25 sales partners worldwide.

Materials and Processes
Electrical Steel
Loose stator and rotor laminations, stamped stacks and stator-rotor assemblies form the magnetic core material of the motors.
Magnet Wire (enameled copper wire)
Used for the windings of the stator and rotor coils.
Sintered Metal
Used for gear components with high dimensional accuracy.
Magnets
Permanent magnets for excitation of DC and BLDC motors.
Carbon Brushes
Current transfer to the commutator in brushed motors.
Die Casting
Die-cast parts serve as motor and gear housings as well as structural components.
Plastic Granulate
Raw material for injection molding of housings, insulation and sealing elements.
Plastic and Rubber Parts
Two- and three-component parts, hybrid parts, sealing and insulation elements as well as hoses.
Stamped, Pressed and Deep-Drawn Parts
Thin metal parts for structures and sheet metal components of the drive systems.
Shafts
Rotating metal shafts as central running components of the motors.
