Project Brushless DC motors

Our Brushless DC motors* development project is taking big steps forward. Our ambitious production technician Gottfrid Wilensjö visits our supplier of production equipment for Brushless DC motors. Here he learns how the winding machines work for the different stator variants.

Things are also happening on the development side. Prototypes are now made of several types of BLDC variants.

It will sure be an exciting autumn!


* A brushless DC electric motor (BLDC), also known as an electronically commutated motor, uses an electronic controller to switch DC currents to the motor windings producing magnetic fields. This control system is an alternative to the mechanical commutator (brushes) used in all other motors from Ankarsrum Electric Motors.

AEM will produce outrunners (the stator is surrounded by the rotor) and inrunners (the rotor is surrounded by the stator). In both cases, only the stator is winded.

The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high efficiency, high durability, and low maintenance. Brushless motors are commonly used in applications with continuous run such a cooling fans and robot welding and also handheld professional equipment. Not to be forgotten – brushed motors have their given advantages in certain applications.
