Geared Motor

The motor can be used in a wide variety of applications by combining it with a reduction gear.
With the precision processing technology cultivated in watchmaking, Adamant Namiki provides geared motors equipped with high-precision gear heads that are quiet and have high transmission efficiency.

Gerahead Types

Supar gearhead

Spur gearhead

  1. base-plate
  2. kana (drive sprocket)
  3. guide
  4. spur (driven sprocket)
  5. bearing
  6. output shaft
  • Most popular gearhead
  • Gear shaft is aligned in parallel with the output shaft
  • No thrust force is generated
  • Rotating direction may differ between input shaft and output shaft depending on the stages.

Spur gear: Gear train using spur wheel, relatively simple structured with fewer number of parts, advantage is less mechanical noise.

Planetary gearhead

Planetary gearhead

  1. base-plate
  2. planetary gear
  3. career plate
  4. internal gear
  5. bearing
  6. output shaft
  • Large reduction ratio can be achieved
  • Considerable torque transmission
  • Input shaft (motor shaft) and output shaft (gear shaft) are aligned in one straight line.
  • Torque is distributed evenly to each planetary gear, so the gear is relatively strong in durability.

Planetary gear: It is called a planetary gear because it orbits around the sun gear. Due to large number of teeth, it is suited for high torque transfer.

* Gear head is sellable only in combination with motor.

By attaching a reduction gear mechanism on the motor output shaft, it can generate high torque/low speed, which motor alone cannot achieve.
Compact motors usually feature high speed, but this speed can be reduced to requested level by combining with a gear head.
Because torque increases in proportion to gear ratio, high torque can be easily achieved even in a compact motor.
While a gear head can help generate high torque, it may influence durability and characteristics failure depending on its accuracy.
Using the precision processing technology nurtured in diamond processing/watch part processing, Namiki manufactures and delivers low noise, high efficiency precision gear heads.
