A direct current motor is an electric motor that converts direct current electrical energy into
mechanical energy. Due to its good speed regulation performance, it is widely used in power
drag. The DC motor is divided into permanent magnet, overexcitation and self-excitation
according to the excitation mode. The self-excitation is divided into three types: shunt
excitation, series excitation and re-excitation. When the DC power supply supplies power to the
armature winding through the brush, the N-pole lower conductor on the armature surface can
flow current in the same direction. According to the left-hand rule, the conductor will be subject
ed to the counterclockwise moment; the armature surface S is the lower part. The conductor
also flows through the current in the same direction, and the conductor will also be subjected
to a counterclockwise moment according to the left hand rule.
This type of slow-press DC motor is developed for customers. It is the research and discussion
the engineer and the customer. It also refers to the motor design database accumulated by
Lihui Motor for 17 years. After many strict tests and adjustments, it has high efficiency.
Advantages such as stepless speed regulation. The motor has been tested by the customer,
the performance meets the customer's requirements, and the operation is stable and reliable.
The spur gear motor is based on the ordinary DC motor, plus the matching spur gear motor,
which can effectively improve the utilization rate in the automation industry. Due to its use and
scope of use, it can be divided into different specifications:

DC gear motor tips:
1. When using a DC spur gear motor, the center axis of the DC spur gear motor must be placed in the middle.
If the middle does not deteriorate, the error of the central axis of the DC spur gear motor will result in
the life of the DC spur gear motor.
2, to be smooth on the level surface, to ensure the stability of the base of the spur gear motor
, and the oil of the oil drain of the spur gear motor must be cleaned. During operation, under
normal conditions, it is not easy to cause a lot of vibration and noise. If there is, it is the
transmission gear damage of the spur gear motor. At this time, the transmission gear must be
added.
3. When moving the component to the output shaft of the DC spur gear motor, it cannot be hammered.
The hammer may be pressed into the drive of the DC spur gear motor to damage the internal compone
nts. In order not to damage the output shaft of the body, a rigid steel coupling must be used.
4. When using DC spur gear motor, employees should not be close to the oil mark. In addition to the
need to operate the DC spur gear motor vent cock and drain cock, etc., can be close.
What should I do if the temperature of the DC gear motor rises too high?
1. The stator windings are short-circuited or grounded between turns, causing the current to
increase, and the regulation loss increases and overheats. If the problem is not serious, simply
add insulation from the head, and the winding should be replaced severely;
2, the bearing damage or excessive wear, so that the stator and the rotor phase rub, can see if
the bearing is loose, the stator and rotor are not properly assembled;
3. If the voltage exceeds the extra voltage of the DC motor by more than 10%, or less than
5% of the additional voltage of the DC motor, the DC motor is prone to heat under additional
load, and the temperature rise is increased. The voltage should be checked and adjusted;
4. The cage rotor broken strip or the wound rotor coil joint is loose, causing the maintenance
network current to be too large and heating. The copper strip rotor can be repaired or replaced
, and the cast aluminum rotor should be replaced by a rotor.
The main role of spur gear motors DC type:
Reduce the output torque while reducing the inertia of the load. The torque output ratio is to
be multiplied by the reduction ratio of the motor output, and the output torque cannot exceed
the rated torque specified on the spur gear dc motor. The reduced inertia is the square of the
reduction ratio.
Compared with the conventional DC machine, the spur gear motor has a speed reduction
mechanism that reduces the speed to the necessary speed and increases the torque. Currently
widely used in the steel industry, machinery industry and so on. Using tips can reduce a lot of
hassle for your work.

Instructions:
(1) When using a spur gear motor, the center axis of the spur gear motor needs to be in the middle, because if it is not deteriorated in the middle, the error of the center axis of the spur gear motor will cause the life of the spur gear motor.
(2) It is best to stabilize on the horizontal plane to ensure the stability of the base of the spur gear motor, and the oil of the oil drain of the spur gear motor needs to be cleaned. In operation, under normal circumstances, it will not produce too much vibration and noise. If there is, the gear of the DC gear motor is damaged. At this time, it is necessary to add some lubricant to the gear. Then install a protective device.
(3) When moving on the output shaft of the spur gear motor, it is not possible to strike with a hammer. If the hammer is blown, the drive of the spur gear motor will be pressed in, which may cause damage to internal parts. The use of a steel fixed coupling is required to prevent the output shaft of the fuselage from breaking.
(4) When using a spur gear motor, the worker should not be close to the oil mark under normal circumstances, except that some operations such as a vent plug or a drain plug are required for the spur gear motor. Before use, the accuracy of the spur gear motor should also be carefully checked, such as how the fasteners are, and whether the components can be flexibly rotated. Ensure that the operation can work in a stable, non-impact, vibration-free, non-leakage environment.
