Flipping through vfds, soft starters, and motor controls can put two very different tools side by side: a variable frequency drive that changes how an existing motor runs, and an industrial vibration motor that creates the shake itself. The choice comes down to what your machine needs.
Quick Verdict
If your setup has a three-phase motor but only a single-phase supply, the variable frequency drive is the tool for the job. If you need a compact vibrating screen to shake parts or material, the industrial vibration motor is the simpler, ready-to-run option.
Price and Capability at a Glance
| Feature | 7.5KW VFD | 120W Vibration Motor |
| List price | USD 119.34 | USD 57.07 |
| Input | 220V AC, 1 or 3 phase | 110V AC, 1 phase |
| Output or rating | 3-phase 220V, 7.5KW / 10HP, 20A per phase | 120W, 3600rpm vibration |
| Control | SPWM drive, 0-400Hz, digital and analog terminals | Stepless speed regulator |
| Condition or warranty | New | New, with 3-year warranty |
Where Each Product Wins
The VFD wins any project where you want speed control or phase conversion for a three-phase motor. The vibration motor wins when you need a complete shaking component for a small screen and want plug-in simplicity.
Product Notes
1-To-3 Phase VFD
This drive turns single-phase 220V input into three-phase output, so it can bring three-phase machinery online even when your shop only has single-phase power. It uses SPWM control and offers two sets of terminal functions with digital and analog control terminals, giving you more wiring flexibility for control signals. That makes it a strong fit for constant-torque loads such as air compressors and HVAC units, and for variable-torque loads like pumps and fans. The trade-off is that this is a controller, not a motor: you still need a compatible three-phase motor to produce motion. If your machine already has that motor, the VFD becomes the missing piece between your power supply and your equipment.
110V Vibration Motor with Controller
This motor brings its own motion to a small vibrating screen. The pure copper carbon brush motor is rated at 120W and 3600rpm, and the included stepless speed regulator lets you adjust the vibration level instead of settling for one fixed speed. The aluminum alloy housing keeps the unit compact, and a 3-year warranty is included with the new condition. The limitation is capacity: this component is built for smaller vibrating equipment, and 120W is not going to move a large three-phase machine. If your project is a compact screen or feeder that needs shake on demand, it fits that role directly.
Final Choice by Use Case
- Buy the 1-to-3 phase VFD for $119.34 if you need speed control and phase conversion for a three-phase motor on a single-phase supply.
- Buy the 1-phase vibration motor with controller for $57.07 if you need a self-contained shaker for a small vibrating screen.
