CRRC Construction Motors

CRRC construction motors series is a family of robust, high-performance drive solutions engineered specifically for heavy-duty construction machinery and equipment. The series of motors ranges in rated power from 290 kW to 360 kW and offers dual rated power options (continuous/1 hour) to meet the needs of stable and peak loads.
These motors feature advanced designs, including dual H/H insulation systems, shunt excitation technology, and high-efficiency ventilation, ensuring reliable performance in harsh construction environments with dust, vibration, and wide temperature fluctuations. With rated voltages of 558 V to 1500 V and speeds up to 2000 r/min, they are fully compatible with mainstream construction equipment systems, providing stable traction and power output for excavators, cranes, and tunneling machinery.
Built on CRRC’s mature high-speed rail motor manufacturing technology, the series delivers high energy efficiency (up to 91%) and low long-term operating costs, making it ideal for large-scale infrastructure projects and heavy construction applications.
