Choosing between a variable frequency drive and a vibration motor can feel like a mismatch, but both belong in the motor-controls conversation. The real question is what load your shop puts on a motor: do you need adjustable speed for a three-phase machine, or do you need a controlled shake for moving and screening material? The answer separates these two picks.
Quick Verdict
Need a variable-speed three-phase motor controller for a 220V machine? The 7.5KW 220V VFD is the one, at USD 158.90. Need a controlled vibration source to move or screen materials on a 110V circuit? The 110V 120W vibration motor with controller is the one, at USD 65.08. Match the tool to the load before you spend.

Where Each Product Wins
Where the 7.5KW VFD Wins
- The right pick when you need to run a 220V three-phase motor from single-phase service.
- Matches constant-torque loads such as hard-starting air compressors and HVAC units, plus CNC router spindles and grinders.
- Supports 48-63 Hz input, so it adapts to common line frequencies.
Where the 110V Vibration Motor Wins
- The lower-cost way to add adjustable vibration to a screen or chute.
- Rated for industrial and food machinery, with a 1.63A draw on 110V single phase.
- The included controller and stepless regulator make setup straightforward for a single-purpose vibratory task.
Product Notes
7.5KW 10HP 220V Variable Frequency Drive Inverter Single To 3 Phase CNC VFD VSD
The 7.5KW 220V VFD handles frequency conversion in one unit. It accepts 220V input on single- or three-phase supply and provides three-phase output to run a 7.5KW/10HP motor. That makes it a practical bridge for CNC router spindles, grinders, and compressors in shops working from single-phase service. The SPWM control mode gives variable-frequency speed adjustment, and the 48-63 Hz input range covers common supply frequencies. The limitation is that it is a 220V device, so it won't help on a 110V circuit, and its 7.5KW rating is far more than a small vibration motor needs. If your work is machine-tool speed control rather than vibration, this is the one.
110V 120W Industrial Vibration Motor 1 Phase For Vibrating Screen W/ Controller
If your job is shaking material through a screen or keeping product moving, this motor includes a controller and a stepless speed regulator for adjusting vibration intensity. The 120W pure copper carbon-brush motor sits in an aluminum-alloy housing with spray molding and is made for industrial and food machinery. It runs on 110V single phase and draws 1.63A, keeping the electrical demand modest. The limitation is its fixed purpose: this is a vibration source, not a general-purpose motor controller. You wouldn't use it to run a CNC spindle or convert single-phase to three-phase power. The 120W output is modest, and the 65dB noise level means it is not silent. For compact vibrating screens, it's the purpose-built option.
Final Choice by Use Case
Pick the 7.5KW 220V VFD when your priority is adjustable motor speed, three-phase output, and enough headroom for 10HP equipment. Pick the 110V 120W vibration motor when your priority is a compact, controlled shake for screens and food-machinery applications on standard 110V power. The right answer depends on the load, not the price tag.
