What are the key points of linear motor knowledge? Next, let the editor take you to understand:
Direct Drive Linear (DDL): The motor is a motor with a flat design and directly coupled with the driven load. Because it eliminates the use of mechanical transmission components, it has excellent performance, rigidity, dynamic speed and acceleration, positioning accuracy and operating efficiency. In addition, the direct drive linear motor has a compact structure, low noise, no maintenance, and runs smoothly. It can be divided into core linear motors and coreless linear motors:
Iron core linear motor:
The iron core linear motor winds the coil on the silicon steel plate, and maximizes the generating force through the single-sided magnetic circuit. This kind of motor adopts a special electromagnetic design to provide the maximum rated thrust. The motor constant Km is high to ensure low heat loss and small cogging force. This kind of motor has a large thrust and is ideal for driving heavy items, and can maintain rigidity during machining and handling.
Ironless linear motor:
The ironless linear motor does not have an iron core or slot for winding the coil. Therefore, the cogging effect of the motor is zero, the weight is light, and there is no gravitational force between the coil group and the magnetic circuit. These features are very suitable for applications that require very small bearing friction, high acceleration for light loads, and the highest constant speed under ultra-low speed conditions. The modular design of the magnetic circuit consists of two rows of magnets, which can maximize the thrust generated and provide a magnetic flux circuit for the magnetic circuit.
