Single-phase textile motor: suitable for small, low-power textile equipment, low cost but limited performance, often used in scenarios with low speed and load requirements.

Three-phase textile motor: with high power, high stability and energy saving advantages, it has become the first choice for medium and large textile production lines, especially in conditions requiring frequent speed regulation or high load.

For details, please refer to the table below.

Comparison dimensions	Single-phase textile motor	Three-phase textile motor
Power type	Single-phase AC (voltage is usually 220V)	Three-phase AC (voltage is usually 380V)
Structural features	1. The stator winding is divided into main winding and auxiliary winding (auxiliary starting) 2. Capacitor or resistor starting is required	1. The stator winding is three-phase symmetrically distributed, and no starting capacitor is required
Starting method	Capacitor starting, resistor starting or shaded pole starting, the starting torque is small	Direct start or step-down start, large starting torque, smooth start
Power range	The power is small, usually below 0.75kW (suitable for small equipment)	High power, from 1.1kW to hundreds of kilowatts (suitable for large equipment)
Speed ​​stability	The speed is greatly affected by the load, and the speed regulation range is narrow	Stable speed, with frequency converter can achieve wide range of precise speed regulation
Efficiency and energy consumption	The efficiency is low and the energy consumption is high (especially when lightly loaded)	High efficiency, significant energy saving effect, suitable for long-term full-load operation
Application scenarios	Small textile equipment, such as household sewing machines, small knitting machines, etc.	Large textile machinery, such as spinning machines, looms, printing and dyeing production lines, etc.
Cost	Low cost (simple structure, few accessories)	High cost (requires three-phase power supply, complex structure)
Maintenance difficulty	Maintenance is relatively simple, but components such as capacitors need to be checked and replaced regularly	High maintenance requirements, need to pay attention to three-phase balance and heat dissipation system

The selection should be based on comprehensive considerations of equipment power requirements, power supply conditions, process requirements and cost budget. The modern textile industry is gradually upgrading to high-efficiency three-phase motors to improve production efficiency and green energy saving levels.
