Other Details

We are a trusted firm, engaged in manufacturing and supplying a quality range of Electric Motor to our esteemed clients. This motor is designed and developed in tandem with the international quality standards. We make use of quality raw material and advanced technology to develop these motors. Clients can avail this motor at a competitive price. Some of the specifications of this motors are mentioned below: Performance:Suitable for 415 volts +- 6 %, 50 C/s +- 3%, motors are continuously rated in rated S1 duty, three phase A.C. Provided with an ambient temperature of 40c, class “B” insulation and site altitude of upto 1000m above mean sea level. All T.E.F.C. squirrel cage motors comply with IS: 325 & dimension according to IS: 2223. RANGE:Standard Three Phase 0.125 HP to (0.09 KW to 15 KW), frame size 56 to 160 L in 2, 4, 6, and 8 Pole design. Single Phase Motors 0.25 H.P. to 3 H.P. ENCLOSURE:Motors have IP-44 protection as defined in IS: 4691. Motors can be offered with IP-54 and IP-55 as per the clients' specifications which gives protection against damaging ingress of dirt and harmful effects of water jet. CONSTRUCTION:Standard motors with single shaft extension are horizontal foot mounted (B3 as per IS: 2253) INSULATION SYSTEM AND WINDING PROTECTION:Motor are supply with class “B” insulation system, class “F” can be supplied on request PTC thermistors in the Stator winding can be offered in customized form. PRESSURE DIE-CAST ROTORS:All rotors are of high pressure aluminum die-cast to make sure improved reliability owing to elimination of joint that exist in a brazed rotor. TERMINAL BOX:Standard location of the M.S. terminal box with two cable conduct entries is on the side of the housing. NOISE LEVEL AND VIBRATION:Motors are manufactured for low noise level. Dynamically balanced rotors having perfect alignment and a fine control on the uniformity of air gap minimize the vibration. BEARING SYSTEM:Bearings are anti-friction ball and roller bearings. Regreasing can be offered as per the clients requirements. The grease used and recommended is lithium based with drop point greater than 160 degree. EARTHING TERMINALS:Each motors have three earthing terminals. One in the terminal box and one on each foot. COOLING AND VENTILATION:Type of cooling is as per IS: 6362. Efficient heat dissipation is effected by guided air flow through motor from rib with help of an external fan. LIFTING HOOKS:Provided with suitable located hooks of adequate strength to lift the motor bodily for the application of installation, alignment, repairs and overhauling. PAINT:All standard motors comes in semi-glossy synthetic enamel paint. We also offer customized solution as per the clients requirement.
