Introduction:
Linear Tracks have many design parameters, one being the size of the motor. MotoSize can validate which Yaskawa motor best works for the design provided.
Data Types Needed
There 12 fields of data needed to evaluate the necessary motor. Many can be found in the gear box catalog and others will derive from the project parameters.
Below is a breakdown of each data type, the required units, and a description of what it is and where to find it.
Data Type Definitions
| Data Type | Units | Notes |
| Linear Load Weight | Kg | Weight of everything sitting on the track |
| Linear Speed | Mm/sec | Speed of the Linear Track |
| Pinion Diameter | Mm | Can be found in gear box selection catalog from the Track Manufacturer |
| Gear Ratio | n:1 | Can be found in gear box selection catalog from the Track Manufacturer |
| Coefficient of Friction | n/a | Provided by the Track Manufacturer |
| Mechanical Efficiency | n/a | Can be found in gear box selection catalog (sometimes use .89) |
| Accel / Decel Time | Sec | Time it takes the carriage to accelerate and decelerate |
| Cycle Stopped Time | Sec | How long is the trolley on track not moving during cycle |
| Cycle Stroke Length | Mm | How long is the track |
| Pinion Inertia | Kg*m^2 | Can be found in gear box selection catalog from the Track Manufacturer |
| Gear Box Input Inertia | Kg*m^2 | Can be found in gear box selection catalog from the Track Manufacturer |
| Additional Motor Inertia | Kg*m^2 | Can be found in gear box selection catalog from the Track Manufacturer |
Selecting the Best Motor
With the data fields filled in, it is simply a matter of selecting a motor from the drop-down menu and selecting the “Evaluate Track” button.
