In all automation systems and smart devices, the motor is often called the “heart of the industry.” It’s not just a drive component—it’s the key element for energy conversion and precise control. From smart home appliances and medical equipment to robotics and industrial automation lines, the performance of the motor directly determines the overall efficiency and stability of the system.
Why are motors so important?
Direct impact on performance: The motor is the power source, determining speed and torque output.
Energy efficiency: High-efficiency motors reduce energy consumption and operating costs.
Extended lifespan: Selecting the right motor minimizes failure rates and ensures longer equipment life.
As energy-saving, intelligence, and efficiency become dominant trends, understanding motor classifications and characteristics is essential for correct selection and cost optimization.
Motors can be classified in several ways, commonly by power supply type, speed characteristics, and control method.
Principle: Operates by forming a magnetic field between the stator and rotor through direct current, driving the rotor to rotate.
Advantages:
Excellent speed regulation, almost linear control.
High starting torque, suitable for frequent start-stop operations.
Limitations:
Complex structure, requires brush maintenance.
Higher cost, lifespan limited by mechanical wear.
Typical Applications: Electric vehicles, CNC machines, medical pumps, precision instruments.
Principle: Uses alternating current to generate a rotating magnetic field in the stator, which drives the rotor.
Advantages:
Simple structure, low manufacturing cost.
Reliable operation, low maintenance.
Limitations:
Requires a frequency inverter for speed regulation, making control systems more complex.
Typical Applications: Fans, pumps, compressors, conveyor systems.
Feature: Rotor speed is synchronized with the rotating magnetic field; speed remains constant.
Applications: High-power and constant-speed operations such as large compressors, pumps, and rolling mills.
Feature: Rotor speed is slightly less than that of the magnetic field; cost-effective and widely used.
Applications: Fans, conveyors, general-purpose machinery.
