Abstract
The utility model relates to a single-bearing electric excitation direct-drive wind generator, which comprises an excitation synchronous motor, wherein the excitation synchronous motor is an electric excitation synchronous motor, and an excitation power supply which is connected with rotor windings of the electric excitation synchronous motor is a direct current power supply. Because permanent magnet excitation is changed into electric excitation, the single-bearing electric excitation direct-drive wind generator saves cost under the precondition that a single bearing is still kept to be used for supporting, and can adjust excitation current at random.
Description
Technical field
The utility model relates to technical field of wind power generator, relates in particular to a kind of single shaft and holds electric excitation direct wind-driven generator.
Background technology
At present, directly drive single shaft and hold wind-driven generator and adopt permanent magnet excitation mostly, after permanent magnet is embedded into rotor core, be fixed on the rotor field spider, rotor field spider holds by single shaft and is installed to the small end that taper is supported.Because permanent magnet is not only expensive, cause this wind-driven generator cost to raise, and this excitation mode excitation is non-adjustable.
The utility model content
The purpose of this utility model is to overcome above defective, and a kind of low price is provided, and the single shaft that excitation is adjustable holds electric excitation direct wind-driven generator.
The technical solution of the utility model is, a kind of single shaft holds electric excitation direct wind-driven generator, and it comprises excitation magnetic synchronization motor, and described excitation magnetic synchronization motor is electric excitation synchronous motor.
The rotor field power supply that winding connects of described electric excitation synchronous motor is DC power supply.
Described a kind of single shaft holds electric excitation direct wind-driven generator, also comprise rotor field spider, slip ring, excitation cable, the interior flexible single shaft of crossing of described rotor field spider holds the small end that is fixed on the taper support, the rotor of described electric excitation synchronous motor is fixed on the cylindrical of rotor field spider, described wheel hub and taper are provided with slip ring between supporting, and the excitation cable is connected to the DC power supply in the wind power generator control system in the rotor winding by slip ring.
Effect of the present utility model is keeping still adopting single shaft to hold under the prerequisite of support, owing to change permanent magnet excitation into electric excitation, not only save cost, and exciting current can be regulated arbitrarily.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The A place partial enlarged drawing of Fig. 2 Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of single shaft holds electric excitation direct wind-driven generator, it comprises excitation magnetic synchronization motor, rotor field spider 1, slip ring, excitation cable 5, rotor field spider 1 interior flexible crosses single shaft and holds 2 and be fixed on taper and support 3 small end, the rotor 4 of electric excitation synchronous motor is fixed on the cylindrical of rotor field spider 1, wheel hub 7 and taper are provided with slip ring between supporting 3, and excitation cable 5 is connected to the DC power supply in the wind power generator control system in the rotor winding by slip ring.
After adopting the utility model, keeping still adopting single shaft to hold under 2 prerequisites that support, owing to change permanent magnet excitation into direct current excitation, not only save cost, and as long as by regulating the size of direct current electric current, the size that can regulate excitation field.
More than be a kind of execution mode of the present utility model, a preferred demonstration example.The scope that the utility model application is asked for protection has more than and is limited to described execution mode.The technical scheme of all and present embodiment equivalence all belongs to protection range of the present utility model.
