About

About EC frameless DT 85 L

EC frameless DT 85 L is supplied as separate rotor and stator components that machine builders install directly inside their own mechanical housing. This construction lets the surrounding joint, bearing arrangement and structural parts serve as the motor enclosure, reducing duplicated material and packaging volume. The large motor diameter and short axial length support high torque production within flat rotary joints and constrained mechanisms.

Integrators pair the motor with an external position sensor, bearings and a maxon or third-party controller selected for the application’s voltage, current and feedback requirements. The kit is used in robot joints, gimbals, exoskeletons and precision industrial axes where the motor must become part of the host structure. Maxon supplies it as a configurable production component with winding and integration options.

Context

Market context

Flat 680 W frameless brushless motor kit for compact, tightly integrated rotary drive assemblies.

  • Target environment: Robot joints, compact actuators, industrial machinery and custom motion systems
  • Workflow context: Embedded rotary actuation where the host assembly supplies the bearings, shaft, housing and thermal path
  • Customer context: OEM motion teams designing a compact actuator around separate rotor and stator components.
  • Deployment model: Commercial motor kit sold through maxon with orderable quantities, CAD data and installation documentation.
  • Commercial maturity: Commercial orderable component with published electrical, mechanical and thermal specifications.
  • Adoption constraints: Integration requires mechanical bearing and shaft design, rotor-stator alignment, commutation, drive selection, cooling and validation across the host duty cycle.
  • Adjacent products: Kollmorgen TBM2G, maxon EC frameless families and other frameless BLDC motor kits
