How To Test A Squirrel Cage Motor Construction
A power analyzer is used for measurement. If the target voltage is achieved without any change in frequency on the graph, then the motor's turn-to-turn insulation is healthy, but any shifts in waveforms indicate weakness in that particular area. The direction of the induced current is such as to oppose the cause producing it. How to test a squirrel cage motor kit. There is compared the influence of the core and mechanical losses sum on the efficiency dependency on the way of this losses components determination. Squirrel cages are typically made from copper or aluminium. 5 and the total power input is equal to the sum of two wattmeter readings.
Ur: terminal reduced voltage according to project IEC 2G/102/CDV. It is cooled by pouring some water into the brake low loads, (when pf< 0. When a 3-φ supply is given to a 3-φ winding displaced by 120◦ in space, a magnetic field of constant magnitude but rotating at synchronous speed is produced. The rotor resistance in the circuit model is. Shaft Condition: Manually rotate the motor shaft to assess its condition. This device uses a DC voltage (100-5000+ V) to detect insulation breakdown inside of a motor. The load is then increased in steps, each time noting down all the above readings. If we have the value of no-load current I0, applied voltage V0, and total core loss, we can determine the magnetizing component Im and energy component Ie, no-load resistance R0, and no-load reactance X0 from the following calculations. It is performed with the rotor completely separated from its stator and connected to an armature growler– a coil of wire wrapped around an iron core connected to a source of AC current. Field testing & inspection of 3-phase squirrel cage motors - Resource Library. Cable Size Calculation for LT & HT Motors. Any shorts will manifest as "hot-spots" on the thermal image, which means that any current through the rotor will unevenly heat those points. The test is performed by a current generator (greater than 10 Adc) and a voltmeter.

Air is drawn through the fan cover grills due to the negative pressure created by the fan, the air is then directed across the motor housing. And also, for the wound rotor, the external resistance should be cut out completely. These tests send pulses at increasing voltages up to the target voltage one phase at a time, generating them in such a way as to simulate startup/slowdown spikes. Disconnecting the motor from power: When you are ready, move the transformer's motor disconnect switch to take it off of power. It provides a test of the quality of insulation resistance (IR), which will start degrading as soon as the motor is in use due to temperature effects. Changing the type of bearing used also changes the design considerably. The lifting eye allows moving of the motor using a strop, rope, crane, chain block or cable etc. Take each end and place it on different permutations of L1, L2 and L3 and record each reading. How to test a squirrel cage motor construction. Each winding is energised in pairs and in sequence to produce a rotating magnetic field. Test new and stored spare motors.
The experiment is repeated for different values of load currents till the rated current of the machine is reached. Induction Motor Components. At either end of the rotor shaft, anti-friction bearings are installed. The amount of power may also vary. How to test a squirrel cage motor wiring. The accelerometer measures vibration acceleration and not velocity, if used, the software converts the acceleration to the velocity by applying the calculation. Polarization index test. Unable to display preview.

Experience (1to 3 years)(3-male candidates required). The voltage is increased till the full-load current flows in the stator. For Report & Tender Department. Integrated counter for the total number of tested and failed rotors, and a complete record of the specific type and frequency of fault errors is recorded. Dust shields may be installed between the shaft and end shields to prevent foreign particles from entering the motor's interior. Some issues, like faulty wiring or a damaged shaft, may require replacing the problematic parts. The two primary assemblies within an induction motor are the stator and rotor; the stator and rotor are however built from smaller individual components. A retaining ring is used to retain the bearing within the motor end cover housing. The exception is European motors, which will have the designations U, V and W. These wires should be tested to determine the health of the motor's power supply. If the applied voltage is significantly lower or higher than specified, this may be one source of your problems. Basics of Motor (and Rotor) Testing. Turn On the Motor: Turn on the motor and locate the terminals.
Capacitor start (cap start) induction motors - used in machines with higher inertia loads and those that require frequent starts e. g. conveyors. The fins of the motor frame serve as heat exchangers and have a large contact surface area, this increases the heat transfer rate from the motor to the air and thus increases the motor's self-cooling capacity. © 2020 Karabuk University. Short circuit fault. The stator is a hollow cylindrical structure with slots on the inner periphery and carries a three phase winding.
How To Test A Squirrel Cage Motor Wiring
The motor overload running phenomenon has dull sound, speed drop, motor temperature rise obviously, current increase significantly, etc. These values are used for the calculation of temperature rise. So the rotor starts rotating in the same direction as the stator magnetic field and tries to catch up with it. Motor testing services are available to help ensure your motor is working correctly by testing certain standard parameters, which can reveal potential risks. There should be little to no variation between each lead combination.
In the case of a wound rotor motor, the stator and rotor resistances are separated by dividing equivalent resistance R01 in the ratio of DC resistance of the stator and rotor windings. The shaft key sits within this groove. While induction motors exist in numerous forms, this article focuses on the 3-phase squirrel cage induction motor design because it is by far the most common type of induction motor.
