Insulated enamel copper magnet wire for miniature motor normally adopts Class 155. Magnet Wire for EV mainly uses enameled flat wire during the degree of 180—240.  Magnet wire including round, square, rectangular, and round bondable magnet wire. 

When you're looking for magnet wire for miniature motors, you'll likely need wire with specific characteristics to ensure optimal performance. Magnet wire, also known as winding wire or enameled wire, is commonly used for winding coils in motors and transformers. 

Here are some considerations for choosing magnet wire for miniature motors:
Gauge (AWG): The gauge of the wire determines its thickness. For miniature motors, you'll likely need a fine gauge wire. The American Wire Gauge (AWG) system is commonly used to specify wire sizes. Smaller AWG numbers represent thicker wires.

Insulation Type: The insulation on the wire is crucial for preventing short circuits and ensuring proper electrical insulation. Different insulation types have varying temperature ratings. Common insulation materials include polyurethane (PU), polyester (PE), polyamide-imide (PAI), and polyimide (PI). Choose an insulation type that suits the temperature requirements of your miniature motor.

Temperature Rating: Consider the temperature rating of the magnet wire. This is especially important in applications where the motor might generate heat. The temperature rating should exceed the expected operating temperature of the motor.

Flexibility: In miniature motors, the wire may need to be flexible to accommodate the compact design. Flexible magnet wire is often used in applications where bending and winding are necessary.

Copper Coating: Magnet wire is typically made of copper that may have different coatings, such as bare copper or tin coating. The coating can affect the wire's solderability and corrosion resistance.

When searching for miniature motor magnet wire, you can find suitable options from electronic component distributors, specialized wire suppliers, or directly from manufacturers. Here are some online platforms and suppliers you can consider:
Digi-Key
Mouser Electronics
Newark
Allied Electronics
