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 Exxon�s new Polyrex� EM grease, which protects motor bearings better, providing improved lubrication life, greater shear stability, and superior resistance to washout, rust and corrosion.
