NHK Spring stock highlights EV rotor gains in new interview

NHK Spring stock was last at JPY 3,431.00 on the Tokyo Stock Exchange on September 28, 2026, with a daily change of -0.64 percent. The latest company-linked development is a joint EV motor rotor project that combines NHK Spring's spring and CFRP technologies with Daido Steel's heavy rare-earth-free magnets.

EV rotor reaches 30,000 rpm

In an interview dated September 25, 2026, MarkLines reported that the companies had jointly developed a high-speed, high-output SPM rotor and a spring-fixed IPM rotor for electric vehicle drive motors.

The SPM design is built for 30,000 rpm, with more than 1.5 times the rotational speed and 50 percent higher output than conventional products. The IPM design uses leaf springs instead of resin, which supports magnet removal and reuse during disassembly.

Quarterly figures add operating context

NHK Spring's latest interim figures provide a second reference point. JPX Market Explorer reported on August 6, 2026, that revenue reached JPY 216.16 billion in the second quarter of 2026, up 8.1 percent year over year, while net income was JPY 15.73 billion. The same report cited EPS growth of 75.5 percent from the comparable period.

That combination gives the rotor story a measurable operating backdrop: NHK Spring is pursuing new electrification applications while its most recent reported quarter showed revenue growth and a sharper increase in earnings per share. The rotor program is still tied to customer presentation and future commercialization, so the technical specifications do not yet equal reported sales.

Dividend date approaches

Income investors also face a dated checkpoint. Simply Wall St reported on September 24, 2026, that the stock would trade ex-dividend on September 29, 2026, for a dividend payment of JPY 33.00 per share scheduled for December 2, 2026.

Stock remains below yearly high

At JPY 3,431.00, NHK Spring stock was 20.94 percent below its 52-week high of JPY 4,340.00 and 66.07 percent above its 52-week low of JPY 2,066.00, based on the September 28, 2026 trading snapshot. Market capitalization stood at JPY 695.1 billion and volume reached 603,100 shares.
