- A metal cylinder will work as rotor, but to improve efficiency a " squirrel cage " rotor or a rotor with closed windings is usually used.
- Available squirrel cage induction motor starting methods include direct-on-line starting, reduced-voltage reactor or auto-transformer starting, star-delta starting or, increasingly, new solid-state soft assemblies and, of course, VFDs.
- "' Forward-curve "' This " squirrel cage " impeller generates the highest volume flow rate ( for a given tip speed ) of all the centrifugal fans.
- At low speeds, the current induced in the squirrel cage is nearly at line frequency and tends to be in the outer parts of the rotor cage.
- The number of bars on the squirrel cage determines to what extent the induced currents are fed back to the stator coils and hence the current through them.
- Unlike the DFIG, the FRC can employ a squirrel cage rotor in the generator; an example of this is the Siemens SWT 3.6-107, which is termed the industry workhorse.
- A blower, in the shape of a drum fan ( also called a " squirrel cage " ), pulls the warm humid air from the room across the coils.
- The squirrel cage winding in some machines provides a damping effect for load or system disturbances, and in this role may be designated as an " amortisseur " windings.
- Large motors operating on commercial power frequency include a " squirrel cage " induction winding which provides sufficient torque for acceleration and which also serves to damp oscillations in motor speed in operation.
- The motor used to drive the pump is typically a three phase, squirrel cage induction motor, with a nameplate power rating in the range 7.5 kW to 560 kW ( at 60 Hz ).
- Crumb has acknowledged that one inspiration for Mr . Natural was a character called The Little Hitchhiker from a comic strip called " The Squirrel Cage " by Gene Ahern, which ran from 1936 1953.
- Because the squirrel cage winding is not large enough to dissipate the heat of continuous operation, large synchronous machines often have protective relays to detect when the machine has fallen out of synchronization with the supply voltage.
- Compared to squirrel cage rotors, wound rotor motors are expensive and require maintenance of the slip rings and brushes, but they were the standard form for variable speed control before the advent of compact power electronic devices.
- The ends of the blades are welded to disks to form a cage like a hamster cage and are sometimes called " squirrel cage turbines "; instead of the bars, the turbine has the trough-shaped steel blades.
- By tapering the profile of the rotor bars to vary their resistance at different depths, or by constructing a double squirrel cage, the motor can be arranged to produce more or less torque at standstill and near its synchronous speed.
- If the rotor of a squirrel cage motor were to run at the true synchronous speed, the flux in the rotor at any given place on the rotor would not change, and no current would be created in the squirrel cage.
- If the rotor of a squirrel cage motor were to run at the true synchronous speed, the flux in the rotor at any given place on the rotor would not change, and no current would be created in the squirrel cage.
- Gene Ahern's topper " The Squirrel Cage ", which ran above his " Room and Board ", is notable because of the repetitive use of the nonsensical question,'" Nov shmoz ka pop ? ", which was never translated yet became a national catchphrase.
- Alternatively, the rotor may be provided with a squirrel cage, so that the motor starts like an induction motor, once the rotor is pulled into synchronism with its magnet, the squirrel cage has no current induced in it and so plays no further part in the operation.
