Abstract
The utility model relates to a motor changing single speed into multi-speed. An electrode stator of the motor is provided with a winding which uses a delta/2Y wiring mode. Six temperature measuring resistors are added on the winding. The stator winding of the motor is changed from B pole insulation to F pole insulation. According to the utility model, by changing the wiring method of the stator winding, different pole numbers can be acquired; due to the fact that the arrangement and the wiring method of the winding are different, the output power and the output torque of the motor are different when the pole number is different; a high-speed wiring method is used for high flow, while a low-speed wiring method is used for low flow; when the motor provided by the utility model is used in a circulating water pump, the circulating water pump runs at different speeds in winter and summer to adjust the flow; and the motor has the advantages of less investment cost, high reliability, simple operation, time saving, reduced loss and improved energy-saving effect.
Description
Technical field
The utility model relates to a kind of motor, refers to that especially a kind of single speed for circulating water pump changes the motor of many speed.
Background technology
Circulating water pump is all generally to adopt the single speed threephase asynchronous on the market, the equipping ruless that carry out adjust flux by the increase and decrease number of units that adopt more, because Seasonal Temperature Difference is large, the unfavorable condition of low load with strong power appears in the time of in the winter time, fail to reach the purpose that reduces loss, energy savings.
Summary of the invention
The utility model, in order to solve the problems of the technologies described above, provides a kind of single speed to change the motor of many speed, makes circulating water pump adjust flux easily, thereby realizes energy-saving and cost-reducing purpose.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of single speed changes the motor of many speed, and the stator of the electrode of described motor has the winding of employing △/2Y mode of connection, sets up 6 cover temperature detecting resistances on winding.This motor is threephase asynchronous.
As preferably, the stator winding of described motor changes the insulation of the F utmost point into by the insulation of the B utmost point.
The utility model threephase asynchronous can obtain different numbers of poles by the connection that changes stator winding, different due to the arrangement of winding and mode of connection, the power output of motor when different number of poles is different from the output torque, adopts during high flow capacity and runs up, adopts during low discharge low-speed running.And circulating water pump changes the motor connection in two seasons of summer in winter, double speed is regulated and is also belonged in essence the speed change adjusting.Therefore, adopt circulating water pump double speed operation adjust flux mode, not only can carry out neatly the operational mode coupling, and mate the proper efficiency of operation that can also make and improve.Also have at present and adopt converter technique to realize, although converter technique has many advantages, Meteorological is high, and environmental requirement is high.Double-speed motor of the present utility model, although need in wiring, switch connection, the expense less investment, reliability is high, easy and simple to handle saving time, after transformation, energy-saving effect is remarkable.
The beneficial effects of the utility model are: the expense less investment, and reliability is high, and easy and simple to handle saving time, reduce loss, improves energy-saving effect.
The accompanying drawing explanation
Fig. 1 is a kind of syndeton schematic diagram that the utility model adopts the delta connection mode.
Fig. 2 is a kind of syndeton schematic diagram that the utility model adopts the 2Y mode of connection.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of single speed of the present embodiment changes the motor of many speed, and as shown in Figure 1 and Figure 2, the stator of the electrode of motor has the winding of employing △/2Y mode of connection, sets up 6 cover temperature detecting resistances on winding; The stator winding of motor changes the insulation of the F utmost point into by the insulation of the B utmost point.In Fig. 1, Fig. 2, A, B, C mean the stator inlet wire, and U1-U2, V1-V2 and W1-W2 mean the stator outlet.
The utility model, according to redesign motor stator winding such as former number of stator slots, winding wire gauge and the number of turn, the modes of connection, redefines cover group parameter; Stator winding changes the insulation of the F utmost point into by the insulation of the B utmost point; Set up the Pt100 temperature detecting resistance on winding, so that monitor; Change the connected mode of binding post, realize that Various Seasonal moves by different rotating speeds, thereby regulate easily the flow of circulating water pump, reach energy-saving and cost-reducing purpose.
