Three Phase Induction Motor

Kirti Engineering’s Three Phase Induction Motors are the epitome of industrial-grade
performance—engineered to deliver reliable, energy-efficient power across a wide range of
demanding applications. Crafted with precision-wound copper windings and high-grade silicon
steel laminations, these motors are designed for maximum efficiency and consistent torque
under continuous operation.


The robust cast iron construction and heavy-duty bearing assemblies provide exceptional
mechanical stability and heat dissipation, ensuring longevity even in harsh environments.
Optimized rotor designs—featuring die-cast aluminum or copper bars—offer high starting torque
without compromising running efficiency.


With a TEFC (Totally Enclosed Fan Cooled) enclosure, these motors are fully protected from
dust, moisture, and other environmental hazards, guaranteeing dependable performance in
challenging conditions. Each motor undergoes rigorous quality checks to meet or exceed global
standards, including IEEE, IEC, and NEMA.
