Original Maxon EC Frameless DT Series Torque Motor for Robot Joint Actuators
Maxon is the pinnacle of precision drive systems worldwide, famously powering NASA's Mars rovers. The EC frameless DT (Disk Torque) series is designed for extreme space-constrained applications demanding uncompromising efficiency. Featuring an internal-rotor frameless design, the stator and rotor are delivered as a kit for direct integration into your machine structure. Leveraging Swiss-engineered magnetic circuits and premium materials, Maxon motors deliver massive instantaneous torque while maintaining exceptionally low heat dissipation—making them the ultimate power source for humanoid hands, legs, and high-end surgical robot arms.
Product Highlights
Swiss Precision Efficiency: Exceptional electromechanical energy conversion extends the battery life of mobile and humanoid robots significantly.
Ultra-Compact Disk Torque Design: The large-diameter, short-length flat profile is perfectly suited for low-profile robotic joint layouts.
Massive Continuous Torque Density: Multi-pole internal rotor design outputs staggering rated torque relative to its extremely light weight.
Minimalist Integration: The housingless and bearingless design allows engineers to highly integrate reducers, encoders, and motors into a single compact module.
Low Thermal Dissipation & High Dynamics: Optimized winding technology reduces resistance losses, allowing the motor to operate in high-performance ranges for extended periods.
Extensive System Compatibility: Pairs perfectly with Maxon's multi-turn absolute encoders (TSX series) and ultra-compact controllers (EPOS4/ESCON).

Frequently Asked Questions
Q: Should I choose Maxon or Kollmorgen frameless motors?
A: Maxon's DT series excels in flat-profile designs and ultra-fast dynamic response, holding a monopoly in the miniature range (38mm and below). Kollmorgen offers a broader range of high-power/high-torque models.
Q: Why is Maxon significantly more expensive than domestic alternatives?
A: Maxon uses premium rare-earth magnets and patented winding techniques. Their efficiency and consistency are aerospace-grade, reducing thermal issues and increasing robot runtime.
Q: Are the rotor and stator installed separately?
A: Yes. Frameless motors require the buyer to design the supporting bearings. We provide detailed documentation to ensure accurate axial and radial positioning.
Q: Do you offer matching controllers?
A: Yes, we recommend Maxon EPOS4 or ESCON drives. They are extremely compact and offer full support for CANopen and EtherCAT protocols.
Q: Can Maxon motors operate in vacuum environments?
A: Maxon offers specific vacuum-compatible models. For standard models, please verify if the grease and insulation meet your specific requirements.
Q: What is the current stock status?
A: We keep popular models (e.g., DT 50 series) in stock. Complex specifications or large orders typically require a 6-10 week lead time from the Swiss factory.
