EC Frameless Flat BLDC Motors

Frameless motor kits offer high torque density and space-saving integration. It consists of only a rotor and stator – with no bearings or motorshaft. With outer diameters of only 43 to 90 mm, they are extremely compact. Rotor and stator are delivered separately and connected only during the assembly of the components. Frameless motors offer maximum torque density and minimum size, high overload capability, low cogging torque, and enough space for cable glands.

The DC motor features an integrated printed circuit board with Hall sensors and cables that minimize volume by directly soldering to the board. The rotor and stator are delivered separately, and the stator is securely connected to the aluminum flange for enhanced heat dissipation. The precision-manufactured winding ensures optimal fill factors, improving motor performance. This design provides efficient heat management and compactness, making it suitable for high-performance applications requiring minimal space and high thermal stability.
