It is an instance of the MachineTypeData class accessible through the eMotorSolution.CheckPoints.Machine.Type module.
Parameters
- machine_type_init:
str, The type data of the machine. defaults to"IPMSM". - pole_number_expression:
str, The number of poles for the machine. defaults to"8". - topology_init:
str, The topology of the machine. defaults to"Internal Rotor". - machine_name:
str, The name of the machine. defaults to"My Machine".

Example Usage
Here is an example of how to access and modify some of the attributes and methods of the MachineTypeData class:
import eMotorSolution as ems
# Load an existing project
project = ems.load_project("path/to/your/project.json")
# Access the machine type
print(project.machine.type.machine_type)
>> "IPMSM"
# Modify the machine type
project.machine.type.set_machine_type("SPMSM")
# Access the machine name
print(project.machine.type.machine_name)
>> "My Machine"
# Modify the machine name
project.machine.type.machine_name = "New Machine Name"
# Access the modified machine name
print(project.machine.type.machine_name)
>> "New Machine Name"
