The key properties of motor magnets:
Remanence (Br): Measured in kG, remanence indicates the magnetic strength retained in a magnet after removing an external field. It directly affects motor performance and varies with temperature, described by the reversible temperature coefficient (α).
Coercivity (Hci): Measured in kOe, coercivity is the reverse field needed to demagnetize a magnet. It reflects resistance to demagnetization and motor stability under load or heat. Temperature effects are expressed via the reversible temperature coefficient (β).
Energy Product ((BH)max): Measured in MGOe, it represents the maximum energy a magnet can deliver to a magnetic circuit, indicating energy density and efficiency.
Curie Temperature (Tc): The temperature (°C) at which a magnet loses ferromagnetism. It defines the maximum working temperature, crucial for high-temperature motor applications.
Size & Shape: Custom arc length, thickness, diameter, and segment number to fit motor design.
Magnetic Properties: Adjustable Br, Hci, and (BH)max for different loads and temperatures.
