Their proven high quality and rugged cast iron construction backed by a 12 month warranty make the Sharp Squirrel Cage Induction Motors ideally suitable for all industrial applications.

Rating and Standards

Electric Supply:
Three Phase motors are suitable for 415V ± 10%, 3 Phase, 50 Hz ± 5% supply. For combination of voltage and frequency maximum variation of 10% is allowed.

Single Phase motors are suitable for 220V ± 10%, 50Hz ± 5% supply. For combination of voltage and Frequency maximum variation of 10% is allowed.

Motor of variable voltage and dual voltages can be supplied on specific order / request.

Enclosure:
The standard protection is IP 54/IP 55.

Insulation:
All motors are of Class ‘F’ insulation with temperature rise restricted to Class ‘B’ limits, ensuring reliability and long life.

Duty Rating:
All motors are continuously maximum rated type S1 as per DIN EN 60034-1 at 50Hz, 40ºC and 1000 m. Motors of other duty conditions (S2, S3 etc) can be offered on request.

Ambient:
Standard Motors are designed to operate in an ambient temperature of -20ºC (-4ºF) to 45ºC (113ºF).

Altitude:
Standard motors are designed for operation at an altitude not exceeding 3300 feet (1000 meters) above, sea level. For higher altitudes derating of output kW may be necessary.

Mounting:
Motors are available in foot mounted and flange mounted designs confirming to IEC 72 (Dimensions only)/DIN 42673/ISI231 and IEC 72 (Dimensions only)/DIN 42677/IS 2223 standards respectively.

Construction

Frames and Endshields:
Stator frames and end shields are made from high grade cast iron for exceptional strength and corrosion resistance. They are accurately machined to close tolerance in order to ensure rigid alignment and minimum vibration.

Cooling system:
Cooling fins are cast integrally with Stator frame and endshields. High airflow external fans with stator frames of deep fins construction ensure adequate cooling of the motor. Ensuring extended motor life.

Fan and Fan Cowl:
Polypropylene fans are fitted for effective cooling. Fan cowls are of heavy gauge pressed steel, construction, securely bolted to the motor endshield.

Stator Assembly with Winding:
The integral system of wire, slot and phase insulation and the overall varnish impregnation provide superior winding rigidity capable of withstanding vibration limits.

Bearing:
Standard motors are fitted with high quality double side sealed, C3 Clearance ball/bearings with pre-packed lubricants.

Sharp Tools’ rotating die holders are best suited with wire drawing machines. The rotating die holder reduces die wear by providing a working surface instead of a stationary point. The die life gets extended due to the fact that there is no ovality in the die. The dimensions of the wire are also highly concentric. By experience, it has been found that die life increases to around six times when compared to a stationary die. The less frequently the die is changed, the more the productivity of the wire drawing machine.

Advantages of a rotating die-holder:

• Highest drawing performance and yields
• Better lubrication
• No tunnelling phenomena
• Longer die-life
• No wire ovalization
• Energy saving
• Better finished wire quality
• Maximum machine utilization time
