When you are shopping for motor controls, the first question is not just what you will plug in-it is what the motor needs to do for you. Two options sit near the same price point, but they belong to different corners of the workshop. The 1 to 3 Phase Variable Frequency Drive Inverter 2.2 KW VFD 220 V 3 HP takes a single-phase 220 V supply and gives you a variable-frequency output for a three-phase 3 HP motor. The 110V 120W Industrial Vibration Motor 1 Phase For Vibrating Screen W/ Controller is a self-contained vibration motor with a stepless speed regulator, ready to shake a screen, hopper, or piece of food machinery. Both are new and price within about a dollar of each other, so the practical choice comes down to motion type, not money.
Quick verdict
If your goal is to run a 3 HP three-phase motor from a household-style single-phase feed and control its speed, the VFD is the tool you need. If your project is about physically moving or screening material with vibration, the 120W vibration motor with its included controller is the more direct solution. With prices separated by less than one dollar, choose based on the job, not the price tag.

| Best fit | Motor speed control for 3-phase equipment | Vibrating screens and food/industrial machinery |
Where each product stands out
The VFD is the choice when you already have a three-phase motor and need to feed it from single-phase power. Its narrow, compact body is designed to save cabinet space, and the independent air duct helps heat dissipation, so you can mount units side by side. The external keyboard means you can adjust parameters without leaning into a tight cabinet.
The vibration motor is the choice when you need actual vibration, not just electrical control. It comes with a controller for infinitely variable speed, and the pure copper carbon brush motor gives it a reliable power source for a compact unit. The aluminum alloy housing and spray-molded finish fit well into industrial and food machinery settings.
Product notes
1 to 3 Phase Variable Frequency Drive Inverter 2.2 KW VFD 220 V 3 HP
This is a complete variable frequency drive meant to take single-phase 220V input and deliver three-phase output for a 3 HP motor. The design is compact and narrow, which matters if you are fitting it into a distribution cabinet or a crowded wall. An independent air duct and side-by-side mounting capability let you pack multiple drives without trapping heat. The external keyboard gives you menu access to set functions and confirm parameters, which is helpful in tight workspaces. With an input current of 23A and rated for 10-95% relative humidity without dew, it is a solid control component for industrial use. What it is not is a mechanical motion source: you still need a compatible three-phase motor to actually turn a pump, fan, or conveyor. If speed control for an existing three-phase motor is your goal, this VFD gives you the conversion and control in one package.
110V 120W Industrial Vibration Motor 1 Phase For Vibrating Screen W/ Controller
This is a self-contained vibration motor rated at 120W and 3600 rpm, with a stepless speed regulator included, so you can dial in the vibration intensity you need. It is built for industrial and food machinery, with a pure copper carbon brush motor and a compact aluminum alloy body that measures roughly 18.9 x 11 x 8 cm. The orange finish is applied with spray molding, and the unit is described as easy to install and reliable. For smaller screens, hoppers, and feeders, this gives you a workable vibration package without assembling separate motor and controller parts. The limitation is the power class: 120W is suited to compact equipment and lighter loads, not to large-scale industrial shakers. If your job is consistent, controllable vibration for a modest-sized screen or machine, the included controller and motor combination makes this a convenient, near-$65 solution.
Final choice by use case
Choose the 1 to 3 Phase Variable Frequency Drive Inverter 2.2 KW VFD 220 V 3 HP if you have a three-phase motor that needs variable speed from a single-phase supply, and you want a compact drive with heat-efficient side-by-side mounting.
Choose the 110V 120W Industrial Vibration Motor 1 Phase For Vibrating Screen W/ Controller if you need direct vibration from a compact motor with an adjustable speed regulator for a screen, hopper, or food processing machine.
