IEEE 114-2001 pdf download IEEE Standard Test Procedure for Single-Phase Induction Motors
1.1 Scope
This standard covers instructions for conducting and reporting the more generally applicable and acceptabletests to delermine the performance characteristics of single-phase induction motors, including non-excitedsynchronous motors. It is not intended that this standard shall cover all possible tests used in production ortests of a research nature. The standard shall not be interpreted as requiring the making of any or all of thetests described herein in any given transaction.
1.2 Purpose
This standard test procedure is meant to provide tests for use in evaluating the performance of single-phaseinduction motors.
2.References
This standard shall be used in conjunction with the following standards. If the following standards aresuperseded by an approved revision, the revision shall apply.
3. General tests Single-phase induction motors are normally given a routine test. A routine test includes measurement of input power and input current at no-load, measurement of input current with locked rotor, and a high- potential test. Measurements of input power and input current at no-load and with locked rotor are obtained at rated voltage and frequency. A typical form for reporting the results of a routine test is shown in Form 1, Annex A. Additional tests may be conducted for a determination of efficiency, power factor, starting torque, pull-up torque, breakdown torque, rated-load slip, and load temperature rise. A typical form for reporting these additional test data is shown in Form 2, Annex A. Tests to determine locked-rotor temperature rise, speed- torque characteristics, noise, and vibration may also be conducted.
3.1 Schedule of tests Common types of single-phase induction motors are listed in Table 1 together with tests applicable to each motor type.
Test types in Table 1 correspond to the following as defined in The Authoritative Dictionary of IEEE Standards Terms, Seventh Edition : 6
a) Locked-rotor current
b) Locked-rotor torque
c) Pull-up torque
d) Switching torque
e) Pull-in torque
f) Breakdown torque
g) Pull-out torque
h) Speed
i) Power factor
j) Efficiency
k) Temperature rise
Tests for speed, power factor, efficiency, and temperature rise are usually conducted at rated load; however,these tests may be conducted at any load, as required.
3.2 Tests with load Tests with load are made for the purpose of determining efficiency, power factor, speed, and temperature rise. Some of the miscellaneous tests outlined in Clause 11 are also made with load. For all tests with load, the motor shall be properly aligned and securely fastened. For readings to be used in performance determinations, the motor temperature rise shall be between 50% and 100% of rated temperature rise. The usual procedure is to take readings at higher loads first and follow with readings at lower loads.
