Micromotors | Coreless BLDC motors | SVTN A 03-3673-12-S-1

2 Pole Brushless DC Motors with Integrated Electronics

SVTN A 03-3673-12-S-1 micromotor for coreless motor brushless
Coreless BLDC motor

Long Lifetime - High Efficiency - Low Noise - High Reliability No Cogging - Low Inertia - Cost-effective

The benefits of this technology join the simplicity of use of a brushed DC motor with the longevity of a brushless motor, maintaining cost-effectiveness and ease of integration. The lack of cogging is typical of the coreless motors and guarantees a reduced ripple torque, a linear correlation between torque, speed, and low inertia. The miniaturization of the electronics allows maintaining the diameter of the motor unvaried with a slight increase in length.

Advantages

  • Winding technology without metal bodies
  • Good heat dissipation and high overload capacity
  • Long life expectancy

Benefits

  • Light and compact, easy integration
  • High reliability
  • Good return on investment
  • No need for external drive
