Tangent Drive Motor Mass Moment of Inertia Equation
Use these equations to determine the Inertia of a tangent drive system. Tangent drive may be the following: Timing belt and pulley, Chain and sprocket, rack and pinion, etc...
Tangent Drive System
Conveyor System
Equation:
Motor Speed:
Load Torque:
Friction Torque:
Load Inertia:
Total Inertia
Where:
| Sm = | Motor Speed, rpm |
| Vl = | Load Speed, rpm |
| R = | Radius, in |
| Fl = | Load Force, lb |
| Tf = | Friction Torque, in-lb |
| Ff = | Friction Force, lb |
| Tl = | Torque of Load, lb-in |
| Jl = | Load Inertia, lb-in.-sec2 |
| Wlb = | Weight of load plus belt, lb |
| g = | Gravitational constant, 386 in./sec2 |
| Jp1 = | Pulley Inertia, lb-in.-sec2 |
| Jp2 = | Pulley Mass Moment of inertia, lb-in.-sec2 |
| Jm = | Motor Mass Moment of inertia, lb-in.-sec2 |
| Jt = | Total Mass Moment of Inertia, lb-in.-sec2 |
