Is High-Temperature NdFeB Mandatory for E-Bike Mid-Drive Motors?

Is High-Temperature NdFeB Mandatory for E-Bike Mid-Drive Motors?

As a professional Wholesale bulk neodymium magnets supplier and Custom NdFeB magnets manufacturer, we often receive inquiries about magnet grade selection for electric bicycle mid-drive motors.

E-bike mid-drive motors bear heavy loads during climbing hills and long-hour continuous operation, generating massive internal heat. Ordinary standard neodymium magnets will suffer irreversible demagnetization under sustained high heat, shortening motor service life drastically. We highly recommend N42SH and N45SH sintered NdFeB grades, which stably resist temperatures up to 150°C while retaining strong magnetic flux, perfectly matching the working conditions of mid-drive motors.

Our neodymium permanent magnets comply with RoHS environmental standards.  our factory supports customized sizes, coatings, magnetization directions for BLDC motor magnets, industrial permanent magnets and other industrial magnetic components.

We offer strict quality inspection and global logistics solutions. Whether you need mass magnet orders or personalized custom NdFeB solutions for your industries, our technical team can provide professional  consulting and one-stop manufacturing services.
