How To Test A Squirrel Cage Motor Construction
When looking at the box, you should see six wires, three on each side. Having these tools available will help you avoid leaving the motor unattended. In a no-load test, the motor is running without load. Info – larger motors do not use anti-friction bearings, they use plain bearings. In the case the stator capacitance is too high for the instrument the measurement can be performed phase by phase neutral open. The load is then increased in steps, each time noting down all the above readings. The accelerometer measures vibration acceleration and not velocity, if used, the software converts the acceleration to the velocity by applying the calculation. Types of motor tests. The test measures and graphs the change in current over these 10 minutes, where healthy insulation will "charge", or reduce current, while unhealthy insulation will remain constant. Perfect for testing new and repaired motors prior to acceptance. Also, be sure to disconnect all equipment and wiring that is not going to be included in the testing process. One end of the shaft is the drive end (connected to the load) whilst the other is the non-drive end (usually connected to a cooling fan); both shaft ends have shaft keys for transferring mechanical motion from the shaft to its connections.

Wave patterns are collected from the "surges", providing pulse-to-pulse comparisons that can identify weaknesses in the insulation. Best Value: Costs less than a good Meg-Ohm-Meter offering a quick return on your investment. Three-phase systems are designed differently to fit different needs. A timing tone that supports proper rotation speed during deenergized dynamic test. Each winding is energised in pairs and in sequence to produce a rotating magnetic field. Each test can apply to most AC and DC motors, but each method of testing is dependent on the construction and application of the motor being evaluated. Related Posts: - Short Circuit Test and Open Circuit Test of Transformer. The test applies single-phase power to the motor and the tester slowly rotates the rotor, where an analog meter monitors one phase for any fluctuations in current draw. The recorded temperature should not beyond acceptance range specified in test procedure or motor datasheet.

Next, examine the inside of the motor and the wires involved in the three-phase current. Info - an overheated motor may melt the insulation around the windings and cause the motor to short circuit; this failure mode is unfortunately not uncommon but can easily be avoided providing adequate cooling is always provided. Mechanical (Rotor) tests. The next several three-phase motor tests primarily use this tool, so we will explain how to check a three-phase motor with a multimeter.

Short circuit between poles. In the case of a squirrel cage induction motor, the rotor resistance per phase (referred to as a stator) is derived by subtracting R1 from R01. One side will have terminals labeled L1, L2 and L3 or Line 1, Line 2 and Line 3. And the reduced voltage is supplied to the motor. Some things to look for during this process include: - General Damage: General damage tends to be easy to spot.

Single-phase rotor test. After opening the pliers, the c-clip expands due to residual tensile forces. A sealed ball bearing allows the rotor to rotate without transferring the rotary motion to other stationary parts i. the motor housing. So the rotor starts rotating in the same direction as the stator magnetic field and tries to catch up with it. The laminations do not follow a perfectly straight orientation, but are slightly skewed in order to increase the torque produced. Ui (Uiph): terminal (phase) electromotive force. A DC voltage is applied to the winding and the frame to which the magnetic circuit and other windings are connected. Enjoying this article? The stator contains the insulated windings for the three phases of the motor. Recent flashcard sets. The terminal housing shields the connection board and electrical connections from foreign object damage such as water. In: Bertoldi, P., de Almeida, A. T., Falkner, H. (eds) Energy Efficiency Improvements in Electronic Motors and Drives. The supplied voltage (line to line) is Vs. And due to this voltage, the current cause in the stator winding is Is and the total input power during the short circuit test is Ps.

Hence, for this type of motor, the no-load test is convenient to determine performance parameters. Short circuit fault. This device uses a DC voltage (100-5000+ V) to detect insulation breakdown inside of a motor. Electric motors are highly integrated machines that can develop faults in many areas and, if left unattended, a damaged motor can result in dangerous working conditions.
From no-load test (IEC 34-2); from draft IEC 2G/102/CDV; from presented in this paper method. Dust shields may be installed between the shaft and end shields to prevent foreign particles from entering the motor's interior. The voltage reading should be half of whatever voltage reading was received during the previous test. Our factory-trained and certified technicians maintain excellent turnaround times of one to five days, and we even offer a two-day rush service. Depending upon the design, a rubber dust seal may sit in this space.
