Electric Motor

National Motors® totally enclosed fan cooled squirrel-cage induction motors are designed and manufactured to meet or exceed the latest IEC standards.

These motors have high efficiency, superior speed-torque and excellent electrical characteristics. These multi-purpose motors are the ideal choice for installation in arduous environmental conditions.

This range offers a variety of induction motors with a power rating of 0.75 kW to high powered motor providing 315 kW. These motors are highly engineered to cope up with sudden load increase, longer thermal life, higher altitudes and voltage variations. All the motors are manufactured under strict quality control procedures (ISO 9001) and are fully tested against the applicable standard.
