In the field of machinery, "motor" and "engine" are usually the same thing. Both of them refer to devices designed to convert energy forms into specific mechanical energy.
In the field of machinery, "motor" and "engine" are usually the same thing. Both of them refer to devices designed to convert energy forms into specific mechanical energy.
There are many types of industrial motors. For example, a heat engine is a type of internal combustion engine that burns a specific type of industrial fuel to generate heat, which is then used for mechanical works. /p>
The electric motor can convert electrical energy into mechanical motion. Pneumatic motors use compressed air as the power source, and spring motors in clockwork watches use elastic energy as the power source. In the machine tool industry, when people talk about electric motors, it usually refers to the power unit in axis motion and automation auxiliary equipment, such as linear motors, brushless motors, and so on.

Linear motors are devices that can produce general linear motion without a transmission system. The transmission system generally includes many components, such as racks and pinions, ball-and-lead screws, cams, etc. In rotary electric motors, all of the above general components are required to constitute an electric motor.
The design of the brushless DC linear motor is a slotted stator with magnetic teeth and a moving actuator. Actuators usually have permanent magnets and coil windings. In order to obtain linear motion, the motor controller attracts the coil windings in the actuator, which leads to the activation of the magnetic field, thereby achieving a linear effect.
Besides the linear motor, here we will also introduce another one, the BLDC motor, giving a comprehensive picture of the motor inventory. BLDC motor is the abbreviation of brushless DC electric motor, also known as electronic commutation motor (referred to as ECM or EC motor) or synchronous DC motor. BLDC motors are synchronous motors that are driven by direct current through an inverter that sends out alternating current to excite each phase of the motor through a closed-loop controller.

The controller provides current pulses to the motor windings to control the torque and speed of the motor equipment. Generally speaking, the structure of a brushless motor is the same as or similar to a permanent magnet synchronous motor (PMSM for short). The former can be regarded as a switched reluctance motor or an induction motor, but not a synchronous motor.
Compared with brushed motors, brushless motors have a higher power-to-weight ratio, higher speed, better electronic control, and lower maintenance costs. Based on these advantages, brushless DC motors are widely used in many scientific applications. Linear motors and BLDC motors are widely used in the field of machine tools and metal processing and automation. These products are also booming in the market.
Nowadays, in the fields of automation and 3C consumables electrical, manufacturers who need to deal with new types of processing tasks tend to buy machining centers with industrial robotic arm accessories to achieve a wider range of applications.
Although the machine tool is the most basic equipment of the manufacturer and plays a vital role in determining the final quality of the product in the industrial sector, the robot arm or other automated equipment has become the key to the quality of the machine tool.
This has led to the changes in the design of the industrial BLDC motors and machine tools. After inventing the machining center and the programmed control system (CNC, computer numerical control), compared with the past, the processing standards have become more and more strict. In addition to CNC machining centers, there are CNC turning centers, CNC milling machines, CNC tapping and milling centers, CNC drilling and milling machines and other customized machineries can be integrated with automated design about the industrial motors.
