What is the range of the current density for the open type motors split phase, capacitor and repulsion start motors?

The typical range of current density for open type motors like split phase, capacitor-start, and repulsion-start motors varies depending on the specific application, motor design, and manufacturer specifications. However, a general range for these types of motors can often be found between 4 to 6 A/mm² (Amps per square millimeter). This range is a ballpark figure meant for general guidance and can vary based on the motor’s specific operating conditions, cooling methods, and the efficiency of the design. The exact current density for a specific motor should be sourced from the motor’s datasheet or manufacturer for accurate and safe operation.
