China Magnet Free Electric Axle System Market Trends and Insights

Government NEV Mandates and Local-Content Rules

Beijing will raise the minimum electric range for plug-in hybrids, significantly increasing the requirement^{[1]“NEV Industry Development Plan (2021–2035),”, Ministry of Industry and Information Technology, miit.gov.cn}. Under the revised dual-credit framework, permanent-magnet motors without domestic traceability will receive zero credits. This adjustment directs OEM investments towards induction and externally excited synchronous systems. Additionally, purchase-tax exemptions are now contingent on achieving a higher battery energy density. This benchmark becomes more attainable when utilizing a lighter, magnet-free motor rotor. Recent export licensing restrictions on overseas shipments of permanent-magnet drive units are encouraging foreign joint ventures to shift towards locally sourced induction modules. Collectively, these regulations establish a protective policy framework that accelerates the localization of magnet-free supply chains and motivates automakers to redesign their drivetrains efficiently.

Rare-earth Price Volatility Accelerates OEM Shift to Magnet-Free Motors

Neodymium-praseodymium oxide prices experienced a significant surge, driven primarily by disruptions in the Strait of Hormuz and the enforcement of stricter export quotas. In response, BYD is adjusting its strategy by increasing production of its induction motor while also advancing research and development on variable-flux permanent-magnet synchronous designs. By eliminating neodymium from their induction systems, OEMs can secure stable long-term pricing. This approach aligns with fleet operators' priorities for maintaining a consistent total cost of ownership (TCO). Urban logistics companies, deploying large numbers of vans annually, are now prioritizing cost stability over minor efficiency improvements. Consequently, they are rapidly transitioning to magnet-free e-axles. The growing demand is driving volume economies, reducing per-unit costs, and further reinforcing the shift away from magnets.

Breakthroughs in Control Algorithms for SR and EESM Motors

Chinese institutes introduced sensorless field-oriented control and model-predictive control techniques, significantly reducing torque ripple in switched reluctance motors. Externally excited synchronous motors achieved real-time field-current modulation, aligning their performance with permanent-magnet torque density across a broader speed range. ZF’s modular e-axle platform features software enabling OEMs to seamlessly switch between asynchronous and synchronous topologies without modifying gearsets. This innovation transforms motor selection into a supply-chain decision, sidelining its role as a performance differentiator. Furthermore, advancements in algorithms have shortened development lead times, allowing medium-sized OEMs to easily qualify multiple motor suppliers. This surge in competition has begun to erode the market share of established incumbents.

Lower Total Cost of Ownership vs. PM E-axles

Fleet operators, tracking costs over multi-year cycles, find that induction drivetrains reduce total cost of ownership (TCO) by a significant margin compared to their permanent-magnet counterparts. These operators avoid the price instability of rare-earth metals, which fluctuate considerably more than copper or electrical steel. With simpler rotors, maintenance requirements have decreased: induction buses now require motor overhauls less frequently than those using permanent magnets. Previously estimated energy-use penalties have narrowed significantly, thanks to SiC inverters achieving higher switching frequencies. Analysis of large bus fleets reveals energy consumption levels that are only slightly higher than the permanent-magnet benchmark, highlighting the economic feasibility of magnet-free systems even under the challenging conditions of dense urban stop-and-go traffic.

Higher Inverter Cost for High-Frequency Operation

SR machines are increasingly turning to SiC MOSFETs, which come at a higher cost than traditional silicon IGBTs. This price increase erodes the bill-of-materials edge that permanent-magnet motors once enjoyed in city cars priced at the lower end of the market. While Tiancheng's larger wafers hold the promise of cost reductions, it's important to highlight that commercial yields are still trailing. Induction motors, while capable of efficient operation with cheaper silicon, experience a slight efficiency dip. As a result, a temporary pricing window has emerged. During this timeframe, premium car manufacturers are likely to stick with magnets, avoiding the extra costs tied to inverters.

NVH and Torque-Density Gap with PM Motors

Even after algorithmic smoothing, SR Motors' cabin noise levels remain higher than those of their permanent-magnet counterparts. Induction units lag in torque density, resulting in housings that are significantly heavier for the same output. BYD's induction unit achieves competitive acceleration using advanced flat-wire windings and direct oil cooling. However, it is noticeably heavier compared to a similar permanent-magnet system. Premium sedans, gauging customer satisfaction on cabin quietness, are reluctant to shift from magnetic to electric. They're waiting for either a reduction in noise-cancellation costs or for algorithmic advancements to bridge the gap.
