Chopra and Sons

Catering to the demands of industries and automobile sector, we offer quality geared electric motors that have gained wide appreciation for quality standards. Specially designed for Indian tropical environment, there is standardization of mounting dimensions for interchangeability and ease of maintenance. These industrial electric motors find wide application in fans, compressors, pumps, crushers, machine tools, material handling, cranes and textiles.

Features:

• Non hygroscopic class F insulation
• Suitable for 415 V + /-10%, 50 Hz +/- 5% and combined variation of +/-10%
• Design ambient - 45 deg C
• Use of cold rolled silicon steel for laminations
• Larger terminal boxes to suit even aluminum cables
• Terminal box rotation steps of 90 deg C
• IP 55 enclosure
• Better dynamic response
• Dynamically balanced
• High efficiency and power factor
• Standardization of mounting dimensions for interchangeability and ease of maintenance

Rated Power Output:

Commercial electric motors is based on continuous running duty S1 with an ambient temperature not exceeding 45 deg C. The altitude must not exceed 1000 M above mean sea level while the relative humidity is up to 100%.
