Drive circuit for reducing motor

Abstract

The invention discloses a drive circuit for a reducing motor, which comprises the reducing motor M, wherein, a third input terminal of the reducing motor M is connected to a null line N, a first input terminal of the reducing motor M is connected on one end of an output circuit of a trigger KR1, and the other end of the output circuit of the trigger KR1 is connected to a live line L; one end of an input circuit of the trigger KR1 is connected to a power supply V, and the other end thereof is connected to the collecting electrode of a triode Q1; the emitting electrode of the triode Q1 is grounded, and the base electrode thereof is connected on an output terminal P0 of a control chip through a resistor R1; and a second input terminal of the reducing motor M is connected with the same circuit as the first input terminal of the reducing motor M. The drive circuit of the invention can simply and effectively realize positive and reverse rotation functions of the reducing motor.

Description

technical field [0001] The invention relates to a circuit applied to a geared motor, in particular to a drive circuit of a geared motor. Background technique [0002] A rotatable turntable is often set on the existing dining table, and the turntable is used as an auxiliary table to place dishes containing dishes. By rotating the auxiliary table, diners on different seats can easily get them The delicacies you want to taste. [0003] However, the rotation of the auxiliary dining table is often done manually, which is not only inconvenient, but also relatively laborious in some cases. Therefore, a developer has developed a drive circuit for a reducer, which drives the reducer to rotate, and the rotation of the reducer drives the rotation of the auxiliary dining table installed on the reducer to realize the function of the electric rotating table. However, the existing electric rotating table, The function is relatively single, and it can only rotate in one direction, which i...
