Barebone axial flux motor

WX FRAMELESS.

Flexible high-performance

FRAMELESS MOTOR FOR TIGHTER ROBOTIC INTEGRATION

The WX Frameless series is engineered to be the heart of your machine. By eliminating the housing and bearings, these axial flux motor kits allow for direct integration into your mechanical assembly, saving critical weight and space. Designed for applications requiring high dynamic response and precision, they deliver maximum power in the most compact footprint possible.

Voltage:

48 V

Operating Temperature:

-40 to 85 °C

Continuous Torque¹:

1.6 Nm

¹ Continuous torque the torque the motor can deliver continuously without reaching a critical temperature. The stated value is based on an application heat dissipation of 9.3 W. If your system removes heat more effectively, the achievable continuous torque will be higher.

² Motor constant indicates how much torque the motor can produce for a given level of heat loss. The higher the motor constant, the more torque the motor can sustain before temperature becomes the limiting factor.
