Overview
The Single Phase Three Phase AC Motor Speed Controller is a robust solution designed for speed regulation of single and three-phase induction motors in industrial and commercial applications. Engineered with advanced VFD (Variable Frequency Drive) technology, this controller balances performance, energy efficiency, and cost-effectiveness, ideal for conveyor belts, pumps, and fans requiring reliable speed control.
Features
Dual Voltage Support:
Single-phase input (220V) for 0.1-2.2kW motors and three-phase input (380V) for 0.75-5.5kW motors, supporting both small-scale and medium-load applications.
Wide frequency range (0-60Hz for single-phase, 0-100Hz for three-phase), with slip compensation ensuring speed accuracy ±0.5% under 100% load.
Energy-Efficient Operation:
Auto-tuning function optimizes motor efficiency (IE2/IE3 compliant), reducing electricity costs by 30% compared to fixed-speed systems.
Sleep mode for low-load conditions, cutting power consumption to 5% of rated load while maintaining quick restart capability (≤200ms).
Reliability & Protection:
IP20-rated enclosure with reinforced heat sink (cooling efficiency +20%), preventing overheating in 40°C ambient environments.
Built-in surge protection (1.2/50μs waveform) and overload protection (1.8x rated current for 60 seconds), compliant with IEC 61800-3.
Ease of Integration:
Simple keypad interface for parameter setting (50+ configurable parameters), with optional PROFIBUS DP module for industrial network integration.
Quick-release terminals reduce wiring time by 50%, suitable for retrofitting into existing control panels.
Application
Suited for diverse industrial systems, this controller is used in:
Warehouse Conveyors: Adjusts belt speed for package sorting, with soft-start reducing conveyor belt stress.
HVAC Systems: Controls fan speed in air handling units, maintaining optimal airflow while complying with ASHRAE 90.1 energy standards.
Water Treatment Plants: Regulates pump speed in filtration systems, reducing water hammer effects by 40% through gradual speed changes.
Woodworking Machinery: Provides stable spindle speed in saws and planers, supporting precision cutting (vibration ≤1.5mm/s).
