PRODUCT GROUP NAME - DC Gear Motor

DC GEAR MOTOR

J D Automation manufacturer DC Gear Motor 120 WATT AND 450WATT is a single, integrated mechanical assembly that combines a high-speed Direct Current (DC) electric motor with an attached speed-reducing gearbox.

 


DC Geared Motor How iIs Work.

DC gear motor is an integrated mechanical system that combines a high-efficiency electric motor with a speed-reducing gearbox. The core motor contains a stator (configured with either permanent magnets or electromagnets) and a wire-wound rotating armature. When an electric current passes through the armature coils, it induces a robust electromagnetic field. This field interacts with the stator’s magnetic forces, generating the rotational torque required to drive the motor shaft.


The Role of the Industrial Gearbox

The attached gear reduction box is engineered to optimize mechanical power output. It mechanically converts the DC motor’s native high-speed, low-torque output into a highly controlled low-speed, high-torque output. Engineers select specific gear configurations within the assembly to meet precise application requirements:

  • Spur Gears: Ideal for cost-effective, low-load applications requiring simple designs.
  • Helical Gears: Designed for smooth, quiet operation and higher load capacities due to angled teeth.
  • Planetary Gears: The premier choice for high efficiency, compact spacing, and maximum torque density.
  • By selecting the optimal gear train, industries can drastically improve mechanical efficiency, minimize operational noise, and extend equipment lifespans.
  • Insulation Resistance: 20 M\Omega measured via 500V DC megger between live windings and the external metal frame after operation.
  • Dielectric Strength: Withstands 1.5 kV AC at 50/60Hz for 1 minute without breakdown (Upgraded to 2.0 kV AC for 3-phase 400V setups).
  • Thermal Rise Limit: 80°C maximum temperature rise above ambient, validated using the winding resistance change technique.
  • Thermal Endurance: Built to Insulation Class F specifications, rated safely for internal hotspots up to 180°C.

Climate Thresholds:

  • Ambient operating temperature range: -10°C to 40°C (Must remain ice-free).
  • Ambient operating humidity range: Must be deployed in a dry, non-condensing atmosphere (Zero dew).
