At present, electromagnetic clutch has been widely used in the production of automatic machine tools. Because the electromagnetic clutch has good transmission performance, it greatly improves the working efficiency of the automatic machine tool. The electromagnetic clutch also has universal skills and functions, with the feasibility of various applications. It is also widely used in packaging machines, printing machines, textile machinery, winding machines and other production fields.

The electromagnetic clutch also has universal skills and functions, with the feasibility of various applications. It is also widely used in packaging machines, printing machines, textile machinery, winding machines and other production fields.
The electromagnetic clutch uses the action of electromagnetic energy to transmit torque from the automatic side to the force side, completing the connection between the mechanical mechanism and the transmission system function transmission. Single-plate electromagnetic clutch has the advantages of small size, compact structure, flexible action, low power consumption, simple operation, etc., and has been widely used.
The electromagnetic clutch can be connected to cut-off, can be braked and stopped, can be rotated and positioned, can also be buffered and stopped, and can also be used when micro-movement is required. Let's take a closer look at the various impacts. When starting or when it is necessary to position the machine, a single-plate electromagnetic clutch and electromagnetic brake can be used to complete the micro-motion.
Electromagnetic clutch is mainly used for automatic parts and driven parts, which can accurately connect and cut off the driven parts. When the demand speed changes, the adjustment speed can be changed without stopping the automatic component. The electromagnetic clutch allows the positive rotation of the load without changing the direction of rotation of the automatic member. The electromagnetic clutch does not need a motor switch to complete the high-frequency operation during the high-frequency operation.
To ensure uninterrupted operation of the electromagnetic clutch, regular maintenance is necessary:
1. Always add lubricant to the moving parts of the electromagnetic clutch.
2. Regularly check the armature stroke length. Because during clutch operation, the armature stroke length will increase due to the wear of the cutting surface. When the armature stroke length cannot reach the normal value, it must be adjusted to restore the braking surface and the small gap between the turntable. If the armature stroke length increases above the normal value, the suction volume may be greatly reduced.
3. When replacing the worn braking surface, the small gap between the braking surface and the turntable should be properly adjusted.
4. Regularly check the fastening degree of bolts, especially electromagnet bolts, electromagnet shell bolts, yoke bolts, electromagnetic coil bolts and terminal bolts.
5. Regularly check the mechanical wear of the moving parts and remove the dust, flower hair and dirt on the surface of the electromagnet parts.
The reasons why electromagnetic clutches are so widely used are as follows:
1. High-speed response: Because it is dry, the torque transmission speed is fast and the action is convenient.
2. Strong durability: good heat dissipation, the use of advanced materials, even if the use of high frequency, high energy, but also very durable.
3. Easy to assemble and maintain: It belongs to the static shape of the magnetic field coil hidden in the ball bearing, so there is no need to take out the middle core, use carbon brushes, and use simple.
No need for wear adjustment: because the structure does not need to adjust the wear of the friction surface. Therefore, no adjustment is required after installation (except for parts).
5. Indeed action: the use of plate grenades, although the vibration is strong, but not loose, with good durability.
6. Adjustable torque, etc.: The friction torque can be adjusted by current and can be used for various purposes.
