SPECIFICATION & PERFORMANCE:-
Motors are continuously rated s1 duty, suitable for 415 volts +- 6%, 50 c/s +- 3%, three phase A.C. supply with class “b” insulation, ambient temperature of 40c and site altitude of up to 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 20 HP (0.09 KW to 15KW) , 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 supplied with IP-54 AND IP-55 on request which provides protection against damaging ingress of dirt and harmful effects of water jet.
CONSTRUCTION:- Standard motors with single shaft extension are horizontal foot mounted.
INSULATION SYSTEM AND WINDING PROTECTION :-Motor are provided with class “b” insulation system, class “f” can be supplied on request PTC thermostats in the stator winding can be supplied on request.
PRESSURE DIE-CAST ROTORS:- All rotors are of high pressure aluminum die-cast to ensure improved reliability due to elimination of joint that exist in a brazed rotor. Each rotor is dynamically balanced along with the fan on electronic machine to ensure very low amplitudes of vibration and noise level.
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 designed for low noise level. Dynamically balanced having perfect alignment and a fine control on the uniformity of air gap minimize the vibration. Pulley, bearing seats and air gap surfaces are grinding resulting in vibration free running.
BERING SYSTEM:- Bearing is anti-fraction ball and roller bearings. Re-greasing can be provided on request. The grease used and recommended is lithium based with drop point greater than 1600.
EARTHING TERMINALS:- All motors have three earthing terminals. One in the terminal box and one on each foot.
LIFTING HOOKS:- Suitably located hooks of adequate strength are provided to lift the motor bodily for the purpose of installation, alignment, repairs and overhauling etc.
PAINT:- All standard motors are painted with semi-glossy synthetic enamel paint. However special paint is available on request.
RELEVANT ISI STANDARD TO MOTORS
GENERAL:-Unbalance motors are a synchronous ac motors with pairs of centrifugal weights fitted to the ends of the motor shafts. The size of the unbalance and with it the amplitude weight the motor is at a standstill. The unbalance motors are also available in special version for mains voltages up to 440V and for a mains frequency ranging from 50 Hz to 60 Hz.
Unbalance vibratory motor with special tough design is used us drive for the vibrating machines. The applications are feeding, screening, discharging, conveying etc. The vibration motors are available in 2800, 1400, 960, and 750 RPM. The special features includes sturdy frame with stiffing ribs, body fabricated with high grade ductile iron, extra large die, of shaft to resist banding under high centrifugal force. Fitted with heavy duty cylindrical roller bearings, specially varnished winding with terminal box to withstand tough operating condition, specially designed electrical parameters for cool operation conditions. vibration motors are available from 0.25 hp to 10 hp in foot mounted design or flange mounted type vibration mounted are widely used in process plants, glass ,food, metal, goal power plant, chemical, ceramic, iron and steel, foundries, packaging industries etc.
