Abstract
The utility model discloses a motor used for a fan-coil unit, comprising a motor shell, a winding fixed in the shell and a temperature protector connected on a zero line of the winding in series. The motor cannot be burnt down in case of faulty connection.
Description
Technical field:
The utility model relates to a kind of motor, especially a kind of fan coil units motor.
Prior art:
Existing fan coil does not have the protective device of wrong circuit with motor, in case the circuit wrong of motor, then motor very likely burns, and has brought unnecessary loss for user or producer.
Summary of the invention:
Even the utility model aims to provide the fan coil units motor that a kind of circuit wrong also can not burn out.
The realization the technical solution of the utility model is: a kind of fan coil units motor is characterized in that: include motor field frame, be fixed on the winding in the housing, be serially connected with temperature protector on the zero line of winding.
Described temperature protector is a positive temperature coefficient thermistor.
Because positive temperature coefficient thermistor is serially connected on the winding zero line, under the normal condition, this resistor presents low-resistance value, does not influence work of the present utility model, in case the circuit wrong, electric current in the circuit increases, the impedance of this resistor increases rapidly, is the high value state, has effectively limited the increase of electric current, winding of the present utility model can not burn, and has prevented that effectively the utility model from not burnt out.
Embodiment
Accompanying drawing 1 is the line map of the utility model embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
Among the utility model embodiment as shown in Figure 1, the utility model has high, medium and low three speed governing shelves, respectively serial connection positive temperature coefficient thermistor 1 in the low-grade zero line of neutralization.During the utility model operate as normal, this thermistor 1 impedance ratio is less, do not influence operate as normal of the present utility model, in case and circuit wrong, electric current in the circuit increases, and the impedance of thermistor 1 increases rapidly, is the high value state, effectively limited the increase of electric current, the utility model can not burn.
Claims (2)
1, a kind of fan coil units motor is characterized in that: include motor field frame, be fixed on the winding in the housing, be serially connected with temperature protector (1) on the zero line of winding.
2, fan coil units motor according to claim 1 is characterized in that: temperature protector (1) is a positive temperature coefficient thermistor.
