The intention of this standard is to establish a framework to measure the efficiency of PWM HVAC Blower Controllers and Brushless DC Motor Controllers and define a usage based overall efficiency. This result can then be used by vehicle OEMs to demonstrate compliance towards...
Users of small electric motors face the difficult task of selecting the best motor for their particular drive application. The technical requirements of the drive, the level of safety needed and the cost factor must all be considered. The choice is made more difficult by the...
This standard covers the minimum requirements for form-wound and bar-wound brushless synchronous machines for use in petroleum, chemical and other industrial applications. This standard includes synchronous motors and generators with two different rotor designs: salient-pole type...
This Standard specifies the test methods to be used in measuring the energy efficiency of small direct-current (dc) and single- and three-phase alternating-current (ac) rotating motors. This Standard includes the following motor types: (a) capacitor, permanent-split; (b)...

Generator class. The generator is classified as a class W, as modified herein. Part or identifying number (PIN). Components that make up the generator systems covered by this specification sheet are identified using the following PIN:
This recommended practice outlines the general requirements of a continuous duty, electric motor-driven brushless alternator unit for supplying 400 Hz electrical power to high performance commercial transport aircraft. This specification is for a single motor-generator set with...
IEC 60034-4-1:2018 applies to three-phase synchronous machines of 1 kVA rating and larger and describes methods intended to be used for machines having an excitation winding with slip-rings and brushes for their supply. Synchronous machines with brushless excitation require special effort...
This specification covers high impact (HI) shockproof alternating current (ac) generator voltage regulator-exciter systems for use on Naval surface ships and submarines. Regulator-exciter systems shall be of the following types, as specified (see 6.2). Type I - Not used. Type II - Rotary...
This standard applies to three-phase synchronous machines of 1 kVA rating and larger with rated frequency of not more than 400 Hz and not less than 15 Hz. The test methods are not intended to apply to special synchronous machines such as permanent-magnet field machines, inductor type machines, etc....
This part of IEC 60034 applies to three-phase synchronous machines of 1 kVA rating and larger. Most of the methods are intended to be used for machines having an excitation winding with slip-rings and brushes for their supply. Synchronous machines with brushless excitation require special...
