High-Efficiency Industrial Motors for Reliable Performance

At Rapidpack, we specialize in manufacturing high-efficiency industrial motors designed to deliver superior performance, precision, and energy savings. Our SI & CI Series motors meet international standards, making them the perfect choice for various industrial applications.

SI SERIES

Motors

3-phase, squirrel cage, IE1 standard efficiency (IEC 60034-30-1) motors in Aluminium die cast frame.

A removable foot mount is integrated in AT Series motors as an additional feature to enhance its capability.

CI SERIES

Motors

3-phase, squirrel cage, IE1 standard efficiency (IEC 60034-30-1) motors in Cast Iron frame.

CT series motors are suitable for continuous S1 duty, under constant load to allow the machine to reach thermal equilibrium.
