High Speed Motor

Uniqueness of Namiki Coreless DC Motor lies in its coil windings.

It is designed for hand tools that require low heat generation and low vibration.

3-phase slot-less brushless motor (sensorless)

[Limit iron loss]

Core, Coil Special design to limit iron loss
Bearing Ceramic bearing

Features

  1. High speed rotation: 40,000 to 90,000rpm
    High speed rotation is achieved with original winding composition and ceramic ball bearings.
  2. Low heat generation: 5 minutes + 5°C/1 hour + 13°C
    Temperature increase is limited when running continuously at 75,000rpm.
  3. Low vibration: Balanced class: G2.5
    Vibration is kept to a minimum level with higher precision parts and rotor balance adjustment.

Iron loss is minimized in this high speed motor.
