Single-Phase to Three-Phase Conversion Explained
One of the most valuable features of the ATO 220V single to three phase VFD is its ability to generate three-phase output from a single-phase power source.
Why This Is Important
- Many small workshops lack three-phase power
- Three-phase motors are more efficient and durable
- VFDs eliminate the need for rotary phase converters
- Power conversion is more compact and efficient
- Motor speed becomes fully adjustable
By using this VFD, users can operate professional-grade three-phase motors without upgrading their electrical infrastructure.
Motor Speed Control and Performance
The ATO 2hp VFD inverter enables precise speed control by varying the output frequency from 0.00 Hz up to 1000.00 Hz.
Benefits of Variable Speed Control
- Smooth acceleration and deceleration
- Reduced mechanical wear
- Improved process control
- Lower energy consumption
- Enhanced equipment lifespan
This level of control is especially useful for fans, pumps, and tools that do not require constant full-speed operation.
Reduced Inrush Current and Motor Protection
When a motor starts directly from the power line, it draws a large inrush current that can damage windings and stress electrical components. The ATO single to three phase VFD minimizes this issue by providing a controlled startup.
Startup Advantages
- Lower starting current
- Reduced voltage drop
- Less stress on motor bearings
- Improved electrical system stability
This makes the VFD particularly suitable for older electrical installations and sensitive power environments.
V/F Control Explained
The ATO VFD uses V/F (Voltage/Frequency) control, a reliable and widely used method for managing AC motor speed.
V/F Control Characteristics
- Maintains constant torque over speed range
- Simple and stable control method
- Ideal for general-purpose motors
- Suitable for fans, pumps, and light machinery
While not as complex as vector control, V/F control is efficient, dependable, and well-matched to the power range of this VFD.
RS485 Communication Capability
The ATO 2hp 1.5kW VFD includes an RS485 communication interface, allowing integration with external controllers and automation systems.
RS485 Benefits
- Remote speed and parameter control
- Connection to PLC systems
- Improved monitoring capability
- Simplified system expansion
This feature adds flexibility for users planning future automation or remote operation.
Wide Range of Applications
Thanks to its adaptable design, the ATO single phase to three phase VFD can be used across many industries and environments.

- Workshop equipment
- Educational and training systems
Its compact size and straightforward configuration make it especially attractive for small-scale and medium-duty motor control tasks.
Energy Efficiency and Cost Savings
Using a variable frequency drive inverter significantly improves energy efficiency by matching motor speed to actual load requirements.
Efficiency Advantages
- Reduced electricity consumption
- Lower operational costs
- Decreased motor heat generation
- Extended motor service life
For equipment that does not need to run at full speed continuously, the energy savings can be substantial over time.
