Product Details:

Nord SK572.1-112MP/4 19.57 AC gearmotor provides controlled torque and speed, ensuring smooth and efficient operation. It is used in conveyor systems, packaging machinery and material handling equipment.

Working Mechanism:

  • Nord SK572.1-112MP/4 19.57 AC gearmotor functions using a three-phase AC motor to convert electrical energy into mechanical power.
  • This motor generates a rotating magnetic field when connected to a power source, causing its rotor to turn and produce mechanical output.
  • This mechanical output is then directed into a gearbox with a 19.57:1 gear ratio.
  • The gearbox reduces the output speed while significantly increasing torque, making it suitable for tasks that require precise control and substantial force, such as driving conveyor systems and heavy machinery.


  • Nord SK572.1-112MP/4 19.57 AC gearmotor has an inline shaft orientation for compact installations.
  • This three-phase gearmotor offer efficient and reliable operation and it is totally enclosed & fan-cooled to prevent dust, moisture and overheating, increasing its longevity in harsh environments.
  • It has a ball bearing to reduce friction and enhance efficiency, offering long-lasting performance.
  • This gearmotor has a lip seal to prevent contaminants from entering, maintaining integrity.
  • It features a die-cast aluminium housing, providing durability while being lightweight.

Frequently Asked Questions:

Q. What is the maximum torque output of this Nord SK572.1-112MP/4 gearmotor?

A. This gearmotor offers a 3540 lb-inch maximum torque output, making it suitable for heavy-duty tasks.

Q. What is the significance of the gear ratio 19.57:1 in this gearmotor?

A. The gear ratio determines how much the motor's speed is reduced and the torque is increased. In this case, for every 19.57 rotations of the motor, the output shaft completes one rotation, providing high torque at lower speeds.

Q. How to maintain this gearmotor?

A. Regular lubrication and visual inspections are necessary to identify and address any damage, leaks or loose components. Also, keeping the gearmotor clean from debris ensures optimal operation and monitoring & maintaining suitable operating temperatures is vital to prevent overheating.
