Baldor Electric has developed a new line of Reliance crusher-duty electric motors that are designed to offer improved reliability, performance and energy efficiency. The crusher-duty motor line is available in frame sizes 180T–449T and in a power range of 5 to 350 hp. According to the company, the entire product line meets current Premium Efficiency energy standards as well as future efficiency standards outlined by the Integral Horsepower Rule, which goes into effect June 1, 2016. Baldor says it enhanced the performance of the crusher-duty motor platform by raising the breakdown and locked rotor torque values across the entire product platform. Flexibility and ease of use have been optimized to provide a drop-in replacement for all frame sizes. Motors configured with roller bearings as standard are field changeable to ball bearings and suitable for across-the-line starting or inverter duty.
