·Electromagnetic clutch mainly uses the principle of electromagnet to control the separation and pull-in of power transmission through DC power supply.
·According to the structure, it can be divided into: single-friction electromagnetic clutch, multi-friction electromagnetic clutch, tooth-clamped electromagnetic clutch, electromagnetic clutch and brake combination.
·According to the performance, it can be divided into: 1. Normally open electromagnetic clutch (separate when power off, pull in when power is on); 2. Normally closed electromagnetic clutch (separate when power off, pull in when power is on).
·According to the application environment, it can be divided into: 1. Dry electromagnetic clutch (used in dry oil-free environment); 2. Wet electromagnetic clutch (used in wet oil immersion ring)
