According to local conditions, combined with working conditions to determine the motor cooling method
The motor cooling method is a very entangled problem in the ordering of high-voltage motors, involving various factors such as cost, installation space and ventilation and heat dissipation effects. Today, Ms. will talk to everyone about the cooling methods commonly used in motors.
Overview of common cooling methods
Rotating motor cooling methods include the nature of the cooling medium, various cooling circuit arrangements and the way the cooling medium is pushed. The cooling methods commonly used in motors are IC01, IC11, IC21, IC31, IC37, IC81W, IC611, IC616, etc.
●Typical cooling method
IC01: Self-cooling type, the fan is mounted on the shaft.
IC11: Self-ventilating with inlet ducts.
IC21: Self-ventilating with air duct.
IC31: Self-ventilating with inlet and outlet ducts.
IC37: Inlet and outlet ducts and separate or separate blower or coolant pressure source
IC611: Fully enclosed fan is cold and self-ventilating, and the motor is equipped with a heat exchanger (air to air)
IC616: Fully enclosed internal air self-circulation with independent blower heat exchanger (air to air) on the motor
IC666: Motor with a fully enclosed cooling air circulating in a motor with a separate air/air cooler.
IC81W: Fully enclosed air-cooled self-ventilating, with a heat exchanger (air to water) on the motor, and the water circulation is powered by an independent water pump or water system.
The IC86W motor has a fully enclosed motor with a separate air/water cooler.
● Cooling medium code meaning
The cooling medium code is “flag letter” + “cooling circuit arrangement code” + “primary cooling medium code” + “primary cooling medium motion pushing method” + “secondary cooling medium code” + “secondary cooling medium motion driving method” .
For example, IC86W is fully labeled IC8A6W7, which means: “IC” is the logo letter (international general cooling symbol), “8” is used to represent the external cooler (using remote medium), and “A” is used to characterize the primary cooling medium air. (Can be omitted), "6" indicates that the primary cooling medium is driven by a separate component, "W" characterizes the secondary cooling medium water, and "7" characterizes that the secondary cooling medium is driven by a separate component or cooling medium system (cooling medium) For water and the pushing method is 7, the number 7 can be omitted).
