Electromagnet related terms

Electromagnet Terms General
Electromagnet force: The thrust or pulling force and suction force generated when the coil of the electromagnet is energized.
Electromagnetic stroke: The distance from the start of the slider movement to the final stop position.
Electromagnet holding force: Pulling force or pushing force of slider at the end of travel ( Om m ).
Electromagnet working period: The ratio of the sum of the power-on time and the power-on/off time.
The electromagnet is continuously energized for 100% of the working cycle: The electromagnet is energized at the rated voltage, which requires that the temperature of the wire circle must not exceed the maximum operating temperature allowed by the electromagnet insulation material.
Electromagnetic gap working cycle: less than 10% of the work cycle. It has one of the longest allowable energizing times to keep its temperature high. For a given product, gap energization can be more powerful than continuous energization. The smaller the work period, the greater the power.
Remanence of the electromagnet: The residual magnetic force after the electromagnet is de-energized. A good design technique will give the product only a few insignificant remanent magnet characteristics.
Maximum operating temperature of the solenoid coil: The maximum operating temperature of the coil cannot adversely affect the organization and function of the material. This temperature is the sum of the ambient temperature and coil temperature rise, which is conventionally 130°C.
Electromagnet ampoule number: The product of the current and the number of turns of the coil, also called NI. It shows the magnitude of the magnetomotive force N I , which is theoretically proportional to the output force of the electromagnet.
Solenoid response time: The length of time that the slide bar is in place after power on. The response time is affected by electrical transitions, starting forces, loads, and travel. When revived, it is affected by remanence.
