Baldor leads the motor industry in applying new technologies and materials to improve motor reliability. Baldor was the first to introduce ISR (Inverter Spike Resistant) magnet wire, which is up to 100 times more resistant to voltage spikes. Baldor was first to use Exxons new Polyrex EM grease, which protects motor bearings better, providing improved lubrication life, greater shear stability, and superior resistance to washout, rust and corrosion.
