Abstract
A rotor for a dynamo electric machine comprises a rotor body 12 defining a plurality of poles in the form of limbs 16 around which windings 18 are provided, and a wedge arrangement 20 spanning the space 42 between adjacent limbs 16 and serving to secure the windings 18 in position, and a discharge passage 44 for delivering coolant to the said space.
Claims10
A rotor for a dynamo electric machine, the rotor comprising a rotor body defining a plurality of poles around which windings are provided, adjacent poles defining a space therebetween, and a wedge arrangement spanning the space between adjacent poles and serving to secure the windings in position, and a discharge passage for delivering coolant fluid to the said space, a coolant passage which extends substantially parallel to the axis of the body adjacent the said space, the discharge passage communicating with the coolant passage to device coolant fluid from the coolant passage to the said space, one end of the coolant passage being closed by an end plate, the other end being closed by a distribution plate formed with grooves defining passages to allow the distribution of coolant fluid to the coolant passage.
A dynamo electric machine comprising a stator and a rotor supported for rotation relative to the stator, the rotor comprising a rotor body defining a plurality of limbs around which windings are provided, adjacent limbs defining a space therebetween, and a wedge arrangement spanning the space between adjacent limbs and serving to secure the windings in position, and a discharge passage for delivering coolant fluid to the said space, a coolant passage which extends substantially parallel to the axis of the body adjacent the said space, the discharge passage communicating with the coolant passage to deliver coolant from the coolant passage to the said space, one end of the coolant passage being closed by an end plate, the other end being closed by a distribution plate formed with grooves defining passages to allow the distribution of coolant fluid to the coolant passage.
