DC motor as a multi-talent for modern vehicles
31.03.2022/XNUMX/XNUMX | The brushless DC motor is a key component for many applications in the Vehicle. The EC motor, which is only about 5 cm small, can be found in the drive to the steering. Schaeffler develops and manufactures DC motors in Bühl with immediate effect. The automotive supplier is thus entering a growing field of business.
The DC motor is becoming increasingly popular when used in modern vehicles: the electric motor can be found in Dual-clutch transmission, hybrid transmission, rear-axle steering, thermal management or seat adjustment. Schaeffler now builds the DC motors itself in Bühl. They are used as standard in a hydrostatic clutch actuator. With the help of the motors, the required pressure is built up here in order to Clutch to operate.
Rotary encoders for axes in drives, machines and systems
"EC motors are true all-rounders and vehicles can no longer be imagined without them," says dr Jochen Schroeder, Head of the Electromobility division at Schaeffler in Bühl. Compared to motors that have mechanical sliding contacts, brushless DC motors are much more durable, more efficient and work much more reliably. Incidentally, the abbreviation EC stands for “electronically commutated”. The electronic commutator electronically changes the voltage from one motor winding to the next.
High level of vertical integration facilitates adjustments
A DC motor from Schaeffler is characterized by the single tooth construction with the stator it contains. The stator teeth are individually stamped, stacked, insulated with injection molding and then assembled into a chain after being wrapped with enameled copper wire. This design offers a significantly higher power density compared to the full cut, in which the laminated core of the stator consists of a closed ring.
"In the production of DC motors, we rely on in-house production from stamping the stator teeth to the finished product,” says Mr. Schröder. This high level of vertical vertical integration offers many advantages. The employees in production can react more flexibly to customer requests for adjustments and continuously optimize production itself, because the entire process chain from the individual part to the finished motor is implemented in Bühl.
Sensor technology protects WKA rotor blade from ice and damage
The complete production line for the series production of the DC motors was realized in just over a year. It is the result of the collaboration of a cross-site teams from Bühl, Höchstadt, Herzogenaurach and Haguenau. The production comprises a total of around 25 process steps. These run fully automated and fully interlinked with two integrated injection molding machines, winding machines and end-of-line testing.
A driverless transport system supplies the system with individual parts and transports the finished products. "The tight schedule could only be met because all employees worked closely together on this project," says Benjamin Hofrth, Head of Operations in the Actuator Systems division at Schaeffler in Bühl. He is responsible for setting up production, in which more than one million DC motors will be manufactured every year from now on.
"For the development and production of future DC motors, our team in Bühl relies particularly on flexibility," says Mr. Hoffarth. This is how a specially developed production kit of stators with three diameter gradations (53 mm, 75 mm and 86 mm) cover different motor sizes and thus different applications. The aim is also to adapt the future EC electric motor portfolio so that it can be used in the areas of actuators, e-mobility and industry as diverse as possible.
Schaeffler is exhibiting at the Hannover Messe 2022.

The users require intelligent networking via bus systems and rapid commissioning. Fulfilling this requires a high power density with minimal installation space and maximum efficiency.
BLDC motors for driving and steering system and shuttle
The new Driving-wheel steering system from EBM-Papst is an innovative drive solution for mobile battery-powered applications. It enables the surfaces to be moved by the vehicles and consists of Motor, Transmission, Sensor and wheel.
EBM-Papst uses the brushless DC motors ECI-63 and ECI-80 in the new drive-steering system or as a direct drive Wheel Drive. The BLDC require little installation space. The brushless DC motors and achieve a high torque with just 24 V. For a short time, the BLDC can deliver three times the output. The integrated intelligence in the motors allows predictive maintenance and condition monitoring in the sense of green intelligence. Together with the Optimax gearboxes, robust, compact and intelligent drives are created.
Shuttles are currently the trend Intralogistik. Nowadays, warehouses are built taller in order to keep a warehouse's space consumption as low as possible. All storage positions on all levels are then approached by shuttle vehicles. The requirements for positioning accuracy, service life and dynamics are also met by the brushless motors ECI-63 and ECI-80 in combination with the Optimax gear units.
