Reduction gear efficiency
This value is a value at the shaft of the motor with a reduction gear.
If the value exceeds the described value, please contact your sales representative.
The reduction gear efficiency differs depending on the reduction ratio. Additionally, the reduction gear efficiency varies depending on operating conditions,
such as the output torque, rotation speed, and temperature.
The value in the table is a typical value for the rated torque at the rated speed and at a room temperature but not a guaranteed value.
The following conversion formula is used for the unit conversion of the backlash: 1 minute = 0.0167°

When the input voltage is low, the torque may be reduced.
The continuous operation torque becomes 80% at 6r/min or lower.
