Frameless Motors

Frameless Motors represent the pinnacle of advanced motion control technology, offering ultra-compact, high-torque solutions for demanding automation and robotics environments. This category encompasses a broad portfolio of brushless DC (BLDC) motors, engineered for direct integration into machinery and systems where space, performance, and flexibility are mission critical. Frameless motors in this category feature stator diameters ranging from 50 mm to 104 mm, enabling seamless pairing with custom mechanical designs, such as robotic joints, rotary actuators, and collaborative automation modules.

• Key Features:
  • Wide stator size selection (50–104 mm) for optimal performance-to-size ratio
  • High output power (up to 5.1 kW) and peak torque (up to 57.3 Nm) to address high dynamic load requirements
  • Sensorless and Hall sensor models for flexible commutation and control strategies
  • Advanced winding topologies, high-efficiency designs (up to 86%), and robust insulation standards (Class B)
  • Modular options including customizable shaft, winding, gear head, and feedback device configurations
• Applications:
  • Collaborative and industrial robotics
  • Precision automation and motion control
  • Robotic joints and exoskeleton actuators
  • Automated assembly systems, packaging machines, and medical devices
• Technical Benefits:
  • Maximum integration flexibility due to frameless (rotor and stator only) construction, supporting direct-drive architectures
  • Enhanced design freedom for engineers—motors can be tailored to specific dimensions and mechanical arrangements
  • Reduced system inertia and backlash, improving responsiveness and positional accuracy
  • High power density enables compact machine footprints without compromising output performance
  • Maintenance-free operation supported by sensorless commutation options and durable componentry

Frameless Motors unite versatility, power, and engineering precision, making them the optimal choice for innovation-driven automation, robotics, and high-performance OEM applications.
