7.2 Rotating direction of the motor output shaft
The rotating direction of the motor output shaft is defined as clockwise (CW) or
counterclockwise (CCW) as viewed from the motor output shaft. However, the
rotating direction of the motor output shaft may vary from that of the gearhead
output shaft depending on the gear ratio of the gearhead.
Rotating direction of the gearhead output shaft
• Geard type
Ratio 5, 10, 15, 50, 100 .................................. Same direction as the motor
Ratio 20, 30....................................................... Opposite direction to the motor
• Combination type parallel shaft gearhead
Ratio 5, 10, 15, 20, 200 .................................. Same direction as the motor
Ratio 30, 50, 100 ............................................. Opposite direction to the motor

• Combination type hollow shaft flat gearhead
At all gear ratios, the output shaft turns in the opposite direction to the motor as
viewed from the front of the gearhead.
With a combination type hollow shaft flat gearhead, the rotating direction will
vary depending on whether the motor unit is viewed from the front or rear of the
gearhead. Check the direction by referring to the figure below.
