Type of cooling circuit

In this section, four choices are available to define the type of cooling circuit topology: None, Zig-Zag, Solenoid, User shape.

By default, there is no cooling circuit. The cooling circuit type is set to “None”.
Important: Access to the “Circuit” area is unlocked when a frame is defined whose shape is circular or square.

Access to the “Cooling circuit” area is unlocked when a frame is defined, when its shape is circular or square.

Remember: The cooling device “Circuit” is not available for outer rotor topology.

User shape cooling circuit

For the user type shape cooling circuit, two circuit sections are proposed: Circular and rectangular.

In both cases, this way of defining the cooling circuit type allows us to consider the theoretical cooling circuit properties by means of length and section even if the real topology is not directly and precisely defined.
