Magnets for sawmill and lawnmower motors

Magnets for sawmill and lawnmower motors

Lawn mower and wood-cutting motor types:
The magnetic properties of the motors in the lawn mower series primarily consist of GC-5H. This provides sufficient remnant magnetism and intrinsic properties, ensuring stable output power and support for the demagnetization curve of the motor as it heats up.

Wind Generator Ferrite Magnet

Wind Generator Ferrite Magnet

Types of DC variable-frequency motors (BLDC):
Variable-frequency motors used in household appliances (BLDC). These were previously powered by high-priced neodymium-iron-boron magnets. However, with the breakthrough in the performance of ferrite magnets and their low cost and superior Curie temperature, they have almost entirely replaced neodymium-iron-bond magnets. The performance characteristics are all GC-9B grade. The residual magnetization is 430 MT, and the intrinsic magnetization is 380 kA/N. Companies such as Hisense, Haier, and Samsung have adopted these motors for their washing machines and air conditioners.

Car seat motor magnet

Car seat motor magnet

Automotive Motor Category:
The most widely used automotive motor today is the GC-5H performance model, with residual magnetism of 410MT, intrinsic magnetism of 270-280KA/M. Given the unique characteristics of automobiles (reciprocating or switching and supporting functions), we have made more optimized changes in the mold magnetic circuit design to better approximate a sinusoidal waveform, particularly in terms of the performance and output characteristics of window operation, seat adjustment, and sunroof motors.

In an era of rare earth price volatility and supply chain uncertainty
In an era of rare earth price volatility and supply chain uncertainty, does your motor design have a “Plan B” for cost control?
Many engineers face a dilemma: chasing high performance with NdFeB magnets, while shouldering soaring costs and supply risks. It’s time to re-evaluate Ferrite Magnets — not as an outdated substitute, but as a strategic choice for cost optimization and supply chain resilience. ✅ Drastic Cost Reduction
Raw material costs are only ~1/10 of NdFeB. For mass production, this means real impact on your bottom line. ✅ Stable & Secure Supply
No more dependence on scarce rare earths. Ferrite’s abundant raw materials ensure a safer, more predictable supply chain. ✅ Reliable Performance
Excellent corrosion resistance and high-temperature stability — no expensive coatings needed. Performs reliably even in harsh environments. Through innovative magnetic circuit design, we’ve helped clients successfully replace NdFeB with ferrite in specific power ranges (e.g., 1–12kW) — for drone motors, power tools, and home appliance motors — significantly reducing BOM costs without compromising performance. Is your next project ready for a more cost-effective power solution? 📩 DM me for a free preliminary feasibility assessment.

Eccentric Ferrite Arc Magnets
Eccentric Ferrite Arc Magnets: What They Are & Their Functions
In the rotor design of permanent magnet motors, magnetic arc segments are key components that directly determine magnetic field distribution and overall motor performance. Eccentric arc magnets (also known as eccentric magnetic tiles) are an optimized structure developed based on standard equal-thickness magnets. What is an eccentric arc magnet? Unlike concentric arc magnets, where the inner and outer arcs share the same center, an eccentric arc magnet has different centers for its inner and outer radii. This special geometry creates a gradually varying thickness across the magnet, from the thickest point to the thinnest point. This design is intentional, not a manufacturing defect — it is a precision-engineered magnetic circuit optimization. Main functions of eccentric ferrite arc magnets Produce a more sinusoidal air-gap magnetic field Reduce magnetic harmonics effectively Lower motor noise, vibration and cogging torque Improve running smoothness and efficiency Typical applications Eccentric magnets are widely used in high-performance motors where low noise and stable operation are critical: Inverter air conditioner compressor motors New energy vehicle drive & auxiliary motors High-speed, low-noise micro motors High-efficiency permanent magnet synchronous motors (PMSM) If you need custom eccentric ferrite arc magnets, rotor magnets, samples or quotations, welcome to contact us for professional support. 📩 shirley@gaumumagnet.com
