Selection steps
■Small geared motor selection steps
- Determination of the Driving Facility
- Specify the driving facility and overall dimensions, then check required conditions for the driving facility, such as the mass and travel speed of the material to be transferred.
↓
- Calculation of rotational speed and load
- Calculate the load torque, loading moment of inertia and rotational speed at the motor driving shaft.
↓
- Confirmation of Required Specifications
- Confirm the required specifications, position accuracies, position holding, speed ranges, operating environment, and environmental resistance, etc. at the drive section and equipment.
↓
- Motor Model Selection
- Select the models most suitable for the required specifications.
↓
- Interim Selection of Motor and Gearhead
- Select motor and gearhead candidates based on calculated rotational speeds, load torque and inertia values as well as the selected motor models.
↓
- Confirmation of the Selected Motor
- Finalize the selection by confirming that all the specifications of the motor and the gearhead adequately meet the requirements.

IDEA NOTE Fixed feed rate using AC motor
A fixed feed rate is achieved using an AC motor and positioning grooves for the workpieces.
IDEA NOTE A single actuator creates lifting and carrying motions.
A parallel link structure is made by linking two eccentric shafts.
IDEA NOTE Dual single bearings
Two single bearing holders are mounted on either side of the thin plate, to serve as a double bearing.
