All about motors and gearheads

PMDC Stock & Geared Motors

  • 6W (1/125 HP) ~ 300W (1/2.5 HP)
  • 12V, 24V, 90V, 3000 RPM
  • Ratio 1/3 ~ 1/2000, 260 in-lbs Max.
  • Permanent Magnet DC Motors are the best solution to motion control and power transmission applications where compact size, wide operating speed range, ability to adapt to arrange of power.
  • Their ability to produce high torque at low speed make them suitable substitutes for gearmotors in many application.
  • Compare to the same size AC motor, it is easy to control the speeds and changes the rotation direction with high efficiency.
  • SPG carries a large supply of DC motors, which are used in numerous industrial applications. 
  • Our Permanent Magnet DC Motors are reliable and consistent performance while offering a high level feature set in both Standard and Custom Permanent Magnet Motors.
  • Sourcing a DC motor to fit your company’s precise application is our goal and we customize design and manufacture reliable, high performing motors.
