Phase converters enable three-phase equipment to operate from an existing single-phase power supply, providing a cost-effective alternative when three-phase service is unavailable or expensive to install. Designed for industrial and commercial applications, they are commonly used to power CNC machines, compressors, pumps, mills, lathes, welders, and other three-phase motor-driven equipment. Available in different configurations and power ratings, phase converters help users select the right solution based on equipment requirements, voltage, and motor horsepower.

How Do I Choose the Right Size Phase Converter?

Choosing the right phase converter is not simply a matter of matching the converter's kW rating to the motor's rated power. Three-phase motors usually require higher current during startup than during normal operation. The required converter capacity depends on the motor rated power, starting method, starting current, load characteristics, and operating conditions.

Before selecting a phase converter, check the equipment nameplate for motor power, voltage, frequency, and full-load current. Then select a converter based on the motor starting method and application requirements.

Phase Converter Sizing Guide by Motor HP

Use the chart below to estimate the required phase converter capacity based on your three-phase motor rated power and starting method.

Motor Power Requirement	Recommended Converter Size	Application Consideration
1 HP (0.75 kW) Three Phase Motor	3–5 HP (2.2–3.7 kW) Phase Converter	Suitable for small motors and light-duty equipment with low starting current.
3 HP (2.2 kW) Three Phase Motor	7.5–10 HP (5.5–7.5 kW) Phase Converter	Common for small machine tools, fans, pumps and workshop equipment.
5 HP (3.7 kW) Three Phase Motor	10–15 HP (7.5–11 kW) Phase Converter	Used for compressors, lathes, mills and other motor-driven equipment.
10 HP (7.5 kW) Three Phase Motor	20–30 HP (15–22 kW) Phase Converter	Consider additional capacity for CNC machines and high starting torque loads.
20 HP (15 kW) Three Phase Motor	40–60 HP (30–45 kW) Phase Converter	Recommended for larger industrial motors, pumps and compressors.
50 HP (37 kW) Three Phase Motor	100 HP (75 kW) Phase Converter	High-power applications may require evaluation of startup current and duty cycle.

Note: The recommended converter sizes above are general references only. Actual selection should also consider the motor starting current, load type, voltage requirements, and whether multiple machines operate at the same time.

Motor Sizing Guide

Motor Starting Method	Recommended Converter Capacity	Typical Applications
Direct-start motor	Motor rated power × 5–7	Machine tools, pumps, compressors, fans, and other direct-start loads
Soft starter + motor	Motor rated power × 3 or more	Equipment using a soft starter to reduce startup current
VFD controlled motor	Motor rated power × 1.5–2	Variable-speed machines controlled by a VFD

Important: Do not select a phase converter by matching converter kW directly to motor kW. Actual sizing depends on motor starting current, load torque, acceleration time, voltage requirements, and operating conditions.
