EC Frameless Brushless DC 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.

Features:

• Printed circuit board with cables and integrated Hall sensors
• Rotor and stator are delivered as separate parts
• Stator packet optimally connected to the aluminum flange, for ideal heat dissipation
• Cables with connectors soldered directly to the printed circuit board to minimize volume
• Precision-manufactured winding for optimal fill factors
• Motor - 43 ... 90 mm
• Motor length - 20.55 ... 42 mm
• Power - 30 ... 260 W
• Nominal torque up to - 1010 mNm
• Max. permissible speed up to 10000 rpm
