Vibrating Motors

Additional Details

SALIENT FEATURES

• Castings for body frame end shields, bearing shields etc., are made out of quality graded grey iron casting which assures fairly long years of utility.
• Pressure die-cast aluminium body for frame 63 to 180 L also available.
• Terminal box 63-90 frame terminal box position on top side.For other frames terminal box position will be right hand side, When viewed and from the drive end,and Terminal box on left hand side can be given on request.Terminal box can be rotated in a step of 90° through 360° for desired direction of cable entries.All terminal boxes are designed for maximum space for ease of connection.
• All motors are supplied with ‘B’ class insulation.Insulation class ‘F’ and ‘H’ can be given on request.
• All standard motors are capable for service factor 1.1 at rated voltage and frequency / or continuous duty.
• Rotors are of squirrel cage , aluminium diecast and are dynamically balanced with a half key to keep the vibration levels very low.
• Core materials are with low loss high grade silicon steel.
• Windings are wound with Polyester enameled ‘F’ class wire & impregnated with thermo setting by varnishing oven.
• All motors are suitable to 415V+/-10%,50Hz +/-5% & combined +/- 10% variations unless otherwise specified.
• All motors can withstand momentary overload of 1.6 times of rated torque, for 15 seconds without stalling.
• Motors are designed for continuous duty at an ambient temp 40° C.
• Thermistors (PTC) can be provided on request to avoid single phasing and over heating due to excess load on the motor.
• Cable gland suitable ¾” to 1” with B.S conduit threadings.Other type of entries can be given on request.
• All standard motors are having deep groove ball bearings.Deep groove ball bearings are capable of taking axial loads in both be direction in addition to the radial loads at high speeds.
• Bearings are double shielded and are adequately filled with lithium based high temp. (up to 120° C) grease.Therefore no relubrication required. Life of the bearing is normally 15000 to 25000 working hours depending upon operating conditions.
• Oil seals are provided to ensure IP 55 protection.
• Noise level of the motors are maintened as per specification IS : 12065
• Motors are tested for vibration level of normal class as per IS : 12075.
