Asynchronous motors (squirrel cage induction motors, the rotor-stator part of slipring induction motors) and the rotor-stator part of synchronous motors are within the scope of increased safety due to the omission of sparks and arcs assuming an appropriate construction of rotor and windings. Tire standards IEC 60079-7 and EN 50019 contain mechanical and thermal requirements that follow this aim. [Pg.200]

AC methods include standard squirrel-cage induction motors, wound rotor induction motors, synchronous motors and commutator motors. Speed variation is obtained by the control of applied voltage to the stator or the control of current and voltage in the rotor by external circuit connections. [Pg.385]

The BOR-60 pumps are driven by standard motors with stepless speed control. For the BN-350 pumps special squirrel-cage induction motors with two speeds (250 and 1000 rpm) are used. For the BN-600 pumps controllable synchronous motors are used coupled to synchronous-rectifier drivers with phase rotors. [Pg.329]

Three-phase, squirrel-cage, IHP motors are the most widely used ac induction motors in industry. Classification of performance requirements has results in NEMA standardized designs that... [Pg.620]

Induction generator This is a standard squirrel cage motor with additional treatment to weather the site conditions. The normal specifications are generally the same as for a standard motor. The permissible voltage and frequency variations are, however, wider as noted below ... [Pg.160]

Today s standard motor enclosure for indoor applications is the open, drip-proof enclosure for induction and high-speed synchronous motors. For large motors, open, drip-proof construction is available up to about 20,000 hp and is used for squirrel-cage, synchronous, and wound-rotor motors. [Pg.259]

Various standard types AC motors are used e.g. squirrel-cage and wound rotor induction motors, variable speed commutator AC motors. [Pg.387]
