Chaitra Engineers

Other Details

We also hold expertise in offering Energy Efficient Electric Motors that are manufactured using quality raw material. These motors are extensively used in various industries like engineering and electronic industries. Our range of Energy Efficient Electric Motors is also known for its high efficiency, low maintenance and rugged construction.

Standard Motors

We are engaged in offering Standard Motors, which are used to avoid single phasing and over heating due to excess load on the motor. In these motors, noise levels are maintained as per the norms and standards of IS : 12065. We also conduct various test regarding the vibration level of these motors according to the IS : 12075 specifications.

 Avoid single phasing and over heating due to excess load on the motor
