BLDC Frameless torque motors - slim profile, massive twisting force

Product feature:
1. High torque
2. Smooth operation
3. high efficiency
4. High precision
5. lightweight
6. excellent heat dissipation performance

 

Thanks to their high copper-fill factor and innovative stator-rotor design, these frameless motors offer superior torque density, exceptionally low losses and highly dynamic performance, while also affording excellent heat dissipation. They may be used as direct drives with reduced motor speed and can be delivered with custom-matching, hollow-shaft safety brakes and absolute encoders.

Frameless servo motors from Maintex are ideal for designers exploring the boundaries of performance in robotics, medical, aerospace, optics and other technically challenging applications.

Frameless BLDC motor, precise control at every degree

1.8 Nm direct drive frameless motor for smooth and stable operation
motor design & optimization
1. High-Precision Magnetic Circuit Design
Skewed slots or fractional-slot windings to minimize cogging torque and reduce torque ripple.
2. Premium Magnetic Materials
High-performance NdFeB permanent magnets and high-permeability silicon steel laminations for enhanced magnetic field uniformity.
3. Low-Harmonic Winding
Optimized winding distribution (e.g., sinusoidal windings) to suppress current harmonics and eliminate torque fluctuations.

520g Ultra-Lightweight direct drive frameless motor 

Advantages:
1. Unmatched Power Density

  • 1.8Nm+ torque in 520g (3.46Nm/kg torque-to-weight ratio), outperforming conventional servos by 40-60%
  • 5x lower rotor inertia vs. traditional motors → 300% faster acceleration (e.g., achieves 0-3000rpm in <10ms for surgical robots)

2. Mechanical Integration Redefined

  • True direct-drive integration: Eliminates housings/couplings, reducing system volume by 30-50%
  • Modular customization: Pre-optimized pairing with harmonic drives (e.g., <50mm ultra-flat joints for cobots)
