The capacitor circuit can be packaged in a box to form the capacitor device. By the motor, the problem that the resistance of a transmission load of the motor is increased when the environmental temperature is reduced can be solved, and the motor is particularly suitable for the gate transmitted by a speed reduction box or a gear pump directly transmitted by the motor for lubricating oil transmission.
Description
Technical field
The present invention relates to the oil pump of a kind of single-phase capacitance electric motor and capacitor device and driving and Dao Zha, in International Patent Classification (IPC), classification can belong to H02K17/08.
Background technology
Traditional single phase electric capacity electric motor is difficult to adapt to the requirement that the oil pump of its transmission, variator or agitator even load work when variation of ambient temperature scope is bigger. The mechanism system of this type of load causes the resistance of motion to increase severely because contained grease viscosity when envrionment temperature reduces increases, and makes electric motor be difficult to smooth transmission. The design visible mechanical industry press version " single-phase asynchronous electric motor and application (resultant current analytical method) thereof " in 1987 of existing all kinds of single-phase capacitance electric motor.
Summary of the invention
Technical problem to be solved by this invention is, it is proposed to the oil pump of a kind of single-phase capacitance electric motor and driving thereof and Dao Zha, it is possible to overcome the problem of ambient temperature effect as stated in the Background Art.
The technical scheme that the present invention solve the technical problem is: a kind of single-phase capacitance electric motor, comprise the capacitor circuit that electric motor winding connects, it is characterized in that: described capacitor circuit comprises the 1st electrical condenser, the 2nd electrical condenser and at the temperature-sensitive switch of envrionment temperature lower than action during prescribed value, and described 2nd electrical condenser is in parallel with the 1st electrical condenser through the moving together contact of temperature-sensitive switch.
The moving together contact of the temperature-sensitive switch of this circuit:
Disconnect when envrionment temperature is higher, the capacitor device that electric motor winding accesses only the 1st electrical condenser, its start-up and operation moment can meet drive environment temperature higher time the requirement of load and temperature rise normal;
Connect lower than during prescribed value in envrionment temperature, 2nd electrical condenser is thus in parallel with the 1st electrical condenser, the electrical capacity that electric motor winding is accessed increases, thus improving start-up and operation moment, the mechanism system overcoming its transmission causes the resistance of motion to increase severely and be difficult to the smooth problem operated because contained grease viscosity when envrionment temperature reduces increases. Now, the temperature rise of electric motor winding raises because the electrical capacity that accesses increases, but winding temperature is still limited in acceptable scope because envrionment temperature is low.
Its further design is: the 1st electrical condenser of described capacitor circuit, the 2nd electrical condenser and temperature-sensitive switch and connection encapsulation thereof, in a box, form capacitor device. This is designed with and is beneficial to the environmental compatibility improving capacitor circuit and conveniently produces installation, especially the load position of electric motor institute transmission is conducive to being installed on, to adapt to the change of load envrionment temperature better, and avoid electromotor winding temperature on the impact of temperature-sensitive switch action characteristic in capacitor circuit.
Its further design be this electric motor drive oil pump and Dao Zha, these oil pumps and road lock especially be applicable to cold district use.
The technical program and effect will be further described in a specific embodiment by reference to the accompanying drawings.
