Product Characteristics

Wide voltage adaptation, strong compatibility

Our controller supports three-phase/single-phase AC input, adapts to grid voltage standards in different regions (such as 220V, 380V, 440V), and can match various AC motor types such as asynchronous motors and synchronous motors, meeting the diverse adaptation needs of industrial transmission equipment.

Vector control algorithm, high speed regulation precision

Our AC motor controller adopts advanced vector control technology, which can perform decoupling control of motor torque and speed. It has a wide speed regulation range (usually above 1:100), stable torque output during low-speed operation, and accurately adapts to the speed regulation requirements of automated production lines and precision conveying equipment.

Multiple protections integrated, safe and reliable

Our controller has built-in multiple protection modules such as overcurrent, overload, overvoltage, undervoltage, phase loss, and overheating. It can quickly cut off the circuit when the motor runs abnormally, and also supports fault code display, which is convenient for operation and maintenance personnel to quickly locate and troubleshoot problems.

Product advantages

Significant energy-saving and consumption-reducing effects

Our AC motor controller optimizes the motor operation curve and automatically adjusts the input power according to load changes, avoiding the "a large horse pulling a small cart" phenomenon when the motor is under light load. Compared with the traditional direct start method, it can reduce electricity consumption by 10% to 30%, and is especially suitable for variable load equipment such as fans and water pumps.

Soft start and soft stop to extend equipment life

Our AC motor controller realizes smooth start and stop of the motor, avoiding damage to motor windings and mechanical transmission components caused by current impact during direct start, effectively extending the service life of the motor and supporting equipment, and reducing equipment maintenance costs.

Intelligent remote control for convenient operation and maintenance

Our controller supports multiple communication protocols and can be connected to PLC and industrial control systems to realize remote speed regulation, parameter setting and status monitoring. No on-site manual operation is required, which improves the automatic management level of industrial equipment and reduces the labor cost of operation and maintenance.

Product Information

What Is AC Motor Controller?

An AC motor controller, often called a Variable Frequency Drive (VFD).AC motor controller is an electronic device designed to regulate the operation of alternating current (AC) motors, including asynchronous induction motors and synchronous motors widely used in industrial applications. It controls key motor parameters such as speed, torque, start-stop mode, and running direction to meet the diverse operational requirements of different industrial equipment.

How it Works (VFD Example)

Rectifier: Converts incoming three-phase AC power into DC power.

DC Link: Smooths and stores this DC power.

Inverter: Uses electronic switches (like transistors) to create a new, variable-frequency, variable-voltage AC output, controlling the motor's speed and torque.

Core Working Principles

1. Voltage/Frequency Regulation (V/F Control)

A basic control method that maintains a constant ratio of voltage to frequency when adjusting motor speed, ensuring stable magnetic flux in the motor stator and avoiding overheating or torque loss during low-speed operation.

2. Vector Control

An advanced control technology that decouples the stator current of the motor into two components: torque current and excitation current. It enables independent and precise control of motor torque and speed, achieving high-precision speed regulation even at low speeds.

3. Direct Torque Control (DTC)

A high-dynamic performance control method that directly adjusts the stator voltage vector of the motor to control the torque and flux linkage, featuring fast response speed and strong anti-interference ability.

Main Functions

1. Soft Start & Soft Stop

Avoids the large current impact caused by direct on-line starting of motors, reduces mechanical wear of the motor and connected transmission equipment, and extends the service life of the whole system.

2. Speed Regulation

Realizes stepless speed regulation of AC motors according to actual load demand, which is widely used in variable load scenarios such as conveyors, fans, and pumps in industrial production lines.

3. Protection Function

Integrates multiple protection mechanisms such as overcurrent, overload, overvoltage, undervoltage, phase loss, and overheating. It can quickly cut off the circuit when the motor runs abnormally and display fault codes for easy troubleshooting by maintenance personnel.

4. Intelligent Control & Monitoring

Supports communication protocols such as RS485 and Modbus, and can be connected to PLC, industrial control systems or upper computer platforms to realize remote parameter setting, speed adjustment and running status monitoring.

Types of AC Controllers

1. Variable Frequency Drives (VFDs): For precise speed and torque control.

2. Soft Starters: Reduce inrush current for gentle starts, limiting mechanical shock.

3. Servo Drives: Offer extremely precise motion control for servo motors.

Typical Application Scenarios

1. Industrial automation production lines (conveying equipment, packaging machinery, assembly lines)

2. HVAC systems (fans, water pumps, air compressors)

3. Hoisting and transportation equipment (crane, elevator, stacker)

4. Precision machining equipment (CNC machine tools, textile machinery, printing machinery)
