Motor starting circuit of medical centrifugal machine

Abstract

The invention discloses a motor starting circuit of a medical centrifugal machine. The motor starting circuit comprises a direct-current power supply, a power supply switch, a fuse protector, a starting button, a stopping button, a first contactor, a second contactor, a third contactor, a time reply, a motor of the centrifugal machine, a first winding, a second winding and a resistor. Compared with the prior art, the motor starting circuit disclosed by the invention can enable the motor of the centrifugal machine to normally operate after the motor is safely started under the rated working voltage, the working stability is better, and because the time reply is adopted, a voltage reducing resistor can be better prevented from shorting connection by the second contactor at the primary time after the motor of the centrifugal machine is started, and the structure is simple. The motor starting circuit can be widely applied to medical centrifugal machines.

Description

technical field [0001] The invention relates to a motor starting circuit, in particular to a motor starting circuit of a medical centrifuge. Background technique [0002] Usually, when we purchase low-speed centrifuges for hospital laboratories, the low-speed centrifuges usually used are used for vacuum blood collection separation, and vacuum blood collection tubes are used. Municipal units have a large number of blood collection tubes to process every day, and usually choose A machine with a large amount of centrifugation at one time has higher requirements on the performance of the centrifuge motor. Today, the motor starting circuit of the medical centrifuge has poor stability and often cannot meet our work needs. Contents of the invention [0003] The object of the present invention is to provide a motor starting circuit of a medical centrifuge in order to solve the above problems. [0004] The present invention achieves the above object through the following technical...
