1.2 About the Device
The direct drive «EC frameless DT» is a high-performance, high-torque, dynamic brushless DC internal
rotor motor (BLDC motor). It is available in various sizes and is designed to be incorporated into a specially
adapted outer body that serves both as the motor’s supporting structure and as torque-carrying device.
The «EC frameless DT» composes two main parts:
•
Stator with electric connections
; for installation into a customer-provided outer body (such as
housing, machine structure, or carrier system)
•
Magnetic rotor
; for on-site assembly with the installed stator and the customer-provided torque-
carrying device
Outer body, motor shaft, and bearings are not part of the «EC frameless DT»’s scope of delivery and are
being designed for a particular case of application by the customer.
Important note on the design
The «EC frameless DT» is a sensorless motor and does not feature any Hall sensor signals. As an option,
maxon offers the «TSX MAG» encoder.
