Characteristics

  • This reduces the vibration in the resonance area of a stepping motor.
  • This supports the follow - up to pulse speed of a stepping motor in high speed zone to improve the max. rotational frequency.
  • Allowable operating temperature: - 10°C to 40°C
  • Bore - completed products. Special processing is not required.

Selection

From the moment of inertia of the rotor of the stepping motor to use, select the applicable part number ofMDRaccording to the following table.
Part Number Moment of Inertia of Stepping Motor's Rotor
MDR-41 5×10-6kg・m2 or Less
MDR-52 1.5×10-5kg・m2 or Less
MDR-57 2.5×10-5kg・m2 or Less
