Abstract

The utility model discloses a motor reversing switch, structurally comprising a motor and a reversing switch. The reversing switch mainly comprises a main winding, an auxiliary winding, a double-pole double-throw switch K1, a centrifugal switch K2, a starting capacitor C2 and a running capacitor C1. The main winding is connected in parallel in a main circuit, then the double-pole double-throw switch K1 is connected with one end of the main winding and then is connected in series with the auxiliary winding which is then connected in series with the running capacitor C1, the running capacitor C1 is connected in parallel with the starting capacitor C2, a branch of the starting capacitor is connected in series with the centrifugal switch K2, then returns to the double-pole double-throw switch K1 after coming out from the centrifugal switch K2, and finally returns to the other end of the main winding after coming out from the double-pole double-throw switch K1, i.e. returns to the main circuit. All the elements are assembled on a printed circuit board and arranged in a switch box body with wiring terminals left out, and then are sealed by using insulating adhesives, thus forming the reversing switch.

Description

The motor commutation switch

Technical field

The utility model relates to a kind of switch, particularly a kind of motor commutation switch.

Background technology

Only having designed one when present motor generally dispatches from the factory turns to.Need be from newly taking motor connecting cartridge apart and just need to change when turning to, and the increase reversing switch, and in some rural areas, the peasant does not know how to use and change circuit under the situation that does not have certain electrician's Knowledge Base, the danger in case wrong will be short-circuited.

The utility model content

In order to have restrained the deficiencies in the prior art, the technical scheme that its technical problem that solves the utility model adopts is: the motor commutation switch, its structure is made up of motor and reversing switch, this reversing switch mainly is made of the circuit board of the switch box body of packing into, it is characterized in that: each electronic component that is installed on the circuit board interconnects the composition control circuit, and described circuit mainly is made of main winding, pair winding, double-point double-throw switch K1, centrifugal switch K2, starting capacitance C2 and running capacitor C 1.Described main winding is parallel in the major loop, bring out from one of main winding and to be connected to double-point double-throw switch K1 and to be in series with one thereafter and to pay winding, be in series with an operation capacitor C 1 after paying winding, and starting capacitance C2 in parallel on the operation capacitor C 1, on the starting capacitance branch road, be in series with a centrifugal switch K2, come out and get back to the double-point double-throw switch K1 from centrifugal switch K2, come out to get back to the main winding other end from double-point double-throw switch K1 and promptly get back to the major loop.Above electronic component is assembled on the printed circuit board, and the switch box body of packing into is reserved terminals, with insulating cement sealing reversing switch.

The utility model benefit: this product has solved above problem, a kind of convenience, reasonable is provided, use simple motor commutation control device, carried reversing arrangement when the user buys motor, need not to increase or change any one parts of motor and can conveniently change turning to of motor.
