Step by step teach you know food machinery factory use dc motor

2020/08/20
At present, food machinery factory has too many, only in cities, for example, the packaging machinery factory, sandwich pot plant, tumbling, factory, Fried factory, such as cleaning equipment factory is much more special. These food machinery factory in equipment production does not have little is to use dc motor. The classification of the dc motor is as follows.



1。 Food machinery factory use dc motor according to the presence of brush classification

was, no brush brush, brushless. Dc motor rotation is continuously on the rotor magnetic field and stator magnetic field of the same, opposites attract. At the appropriate time to convert current through the winding, otherwise can't normal rotating rotor.

( 1) A brush motor

with brush brush dc motor is adopted, Commonly known as the brush) The dc motor. Is to rely on commutator brush motor ( Commonly known as commutator) And brush with alternate current polarity, automatically complete the reversing, commutator and brush inside the motor. A brush motor is divided into two kinds of high speed and low speed. A brush motor external leads for only 2.

a brush motor of the main causes of high failure rate: it is a brush for light wear are prone to failure; Second, magnetic steel cooling condition is poor, easy to demagnetization. Brush wear is not only related to time, but related to the current size and brush gold content, so most of the service life of the brush is about 200. Series motor due to the current is very big, life is mostly to the 200 replacement easier, and the wheel hub motor and column type motor ( Also known as the motor of) The change is difficult.

( 2) Brushless motor

brushless motor is not use brush motor. In order to realize commutation brushless motors by transistors and position sensor ( Hall element) Instead of brush and commutator. Due to this kind of motor is cancelled brush and commutator, so the electromagnetic interference elimination, not only reduces the mechanical noise, and prolong the service life. But this kind of motor control element ( Motor drive and control circuit) Is more complex, increasing the cost, and a slight shake starting at low speed.



2. Food machinery factory use dc motor according to the presence of long magnet classification

according to the presence of magnet for a long time, the motor water magnetoelectric motive and series motor can be divided into two classes.

( 1) Permanent magnet motor

is the permanent magnet motor rotor and stator is only one is made of enameled wire winding winding ( Commonly known as line package) , while another USES a magnet for a long time, Also called magnetic steel) 。 Brushless motors and brushless motor permanent magnet motor divided into two categories.

( 2) Series motor

series motor without using magnets, the rotor and stator winding is adopted respectively, and the two winding in series, so this kind of motor is called series motor. Among them, the stator winding of the magnetic field generated excitation magnetic field.



series motor and control element is two lines, but not like a permanent magnet has a brush motor by exchanging the attachment can change the direction of motor rotation, but by exchange of rotor winding, A pair of lines) Or stator winding ( A pair of lines) Change the direction of rotation.

3。 Food machinery factory using classification of rotating speed of dc motor

points of rotating speed, the motor can be divided into two kinds of high speed and low speed. Speed higher than 3000 / min motor called high-speed motor, motor is called motor at low speed below 1000 / min. At present, there are brush gear hub motor is around 200 r/mn can be done. Due to the high speed motor rotation speed is 3000 ~ 5000 / min, and electric bicycle needs:

( 1) High speed motor speed is about 200 / min, in order to achieve the 0 ~ 20 km/h stepless speed regulation, need through the reduction gear and clutch, so high speed motor are gear motor. Some high speed motor and reduction gear is installed respectively, and some will gear is installed inside the motor, such as brush gear hub motor, the gear in the internal.

the above food machinery factory is the use of the classification of the dc motor, hope to help you.
