Abstract
The invention discloses a stator for a variable frequency motor. The stator is characterized in that: three phase position slots and a co-phase slot are formed in a stator core of the stator, wherein a single-phase metal terminal is arranged in each of the three phase position slots; a three-phase metal terminal is arranged in the co-phase slot; each of the ends of three-phase electric wires of the stator is fixed on the corresponding single-phase metal terminal; each single-phase metal terminal leads out an electric wire; the ends of the electric wires are fixed on the three-phase metal terminal; a single-phase varnished wire clamping groove is formed in each single-phase metal terminal; three single-phase varnished wire clamping grooves are formed in the three-phase metal terminal; the width of the single-phase varnished wire clamping grooves is smaller than the diameter of vanished wires of the stator. The electric wires provided by the invention are clamped in the single-phase varnished wire clamping grooves, and the width of the single-phase varnished wire clamping grooves is smaller than the diameter of the varnished wires of the stator, so that the varnish of the varnished wires of a stator coil does not need peeling during connection, the groove walls of the single-phase varnished wire clamping grooves peel the varnish of the varnished wires, and the stator has the advantage that the varnished wires are easy to connect.
Description
Technical field
The present invention relates to a kind of stator for variable-frequency motor, particularly a kind of stator for roller washing machine variable-frequency motor.
Background technology
Variable-frequency motor adopts special variable frequency induction motor to add the AC speed-regulating mode of frequency converter, and mechanical automation degree and production efficiency are greatly improved; Device miniaturization, high ride; Just replacing traditional mechanical speed governors and DC speed regulation scheme at present.
In variable-frequency motor design in roller washing machine, the plastic end cover of variable frequency motor stator both sides, in order to ensure that inner ring has enough spaces and washing machine complete machine to carry out good assembling, also will ensure enough intensity.
The more random shortcoming of wiring is there is in the stator of existing variable-frequency motor when wiring.
Summary of the invention
The object of the invention is to provide a kind of stator for variable-frequency motor.
For achieving the above object, the technical solution used in the present invention is: a kind of stator for variable-frequency motor, the stator core of described stator is provided with three phase place slots and a common phase slot, described three phase place slots are equipped with a Single Phase Metal terminal, and described common phase slot is provided with a three-phase metal terminal; The termination of the three-phase wire of described stator is separately fixed on a Single Phase Metal terminal, and described Single Phase Metal terminal draws an electric wire respectively, and the termination of this electric wire is fixed on described three-phase metal terminal; Described Single Phase Metal terminal is provided with a single-phase enamelled wire draw-in groove, and described three-phase metal terminal is provided with three single-phase enamelled wire draw-in grooves, and the width of described single-phase enamelled wire draw-in groove is less than the diameter of the enamelled wire of described stator.
Preferred technical scheme is: the termination of the electric wire on described Single Phase Metal terminal and three-phase metal terminal is embedded with adhesive.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1, the present invention first arranges three phase place slots, then couples a wire to common phase slot by three phase place slots, thus has the succinct advantage of wiring.
2, the termination of electric wire of the present invention is embedded with adhesive, therefore has the advantage of good insulation preformance.
3, electrical wire fastener of the present invention is in single-phase enamelled wire draw-in groove, width due to single-phase enamelled wire draw-in groove is less than the diameter of the enamelled wire of described stator, therefore the enamelled wire of stator coil paint connect time without the need to peel off, but the paint of enamelled wire is peeled off by the cell wall of single-phase enamelled wire draw-in groove, has advantage easy to connect.
