Z2 Series Small DC Motors
Product overview
I. Overview
1. Z2 series small DC motors are standard series of small DC motors
issued by the Ministry of Machinery Industry of the People's
Republic of China JB1104-68. It has the advantages of reliable
performance and low price, and is still widely used in printing and
dyeing machinery, packaging machinery, plastic machinery and other
industries.
2. Z2 series small DC motors are divided into 11 frame sizes, and
each frame size has two core lengths. There are three types of DC
motors, DC generators and DC voltage regulating generators, which
are suitable for normal working environment. The motor is used for
general transmission, the generator is used as a general DC power
supply, and the voltage regulating generator is used as a battery
pack.
3. Excitation mode: The motor is shunt or other excitation with a
small amount of stable windings.
The generator is a complex excitation or other excitation magnetic
(generator with a rated voltage of 230 volts); the voltage
regulating generator is a parallel excitation magnetic (without
series excitation winding).
The other excitation magnetic voltage of the motor is made of 110
volts or 220 volts.
The rated voltage of the motor is 110 volts, and there is only one
separately excited voltage of 110 volts.
4. The motor can be driven by V-belt, spur gear or elastic
coupling, and the motor bearing is not used for axial thrust.
5. Z2 series motors can be made into humid tropical (TH) DC motors
with moisture-proof, mildew-proof and smoke-proof properties for
use in humid tropical areas according to the requirements of use,
which should be agreed separately.
Z2 series 2-11# can also be made into a derivative mechanism of
ZYS-A tachometer.
6. The basic series of Z2 series motors are self-ventilated motors.
When the applied armature voltage is lowered to reduce the speed,
the torque will decrease correspondingly with the decrease of the
speed.
7. Z2 series 6-11 motors can also be made into an external blower
structure type, and the blower is installed above the end cover of
the shaft extension end.
8. Z2 series motors are small DC motors for general industrial use.
The motors are suitable for electric drive with a constant power
speed regulation range of not more than 2:1 and an overload
capacity of not more than 1.5 times the rated torque. It can be
used in metal cutting machine tools, paper making, dyeing and
weaving, printing, cement and other industries. The generator can
be used as power supply, lighting or other constant voltage power
supply.
Second, the structure and installation type
1. The motor is a one-way circular shaft extension, according to
user requirements. Can be made into biaxial extension. Frame No.
1-6 motors can transmit rated torque according to the 4th
transmission mode of the overview, while No. 7-11 frame, the shaft
extension of the commutator end is driven by a coupling, which can
transmit rated torque, and uses a triangular The belt-type spur
gear drive can only transmit 50% of the rated torque.
2. The position of the outlet box of the horizontal motor, viewed
from the shaft extension end, is on the left side of the machine
base. According to user requirements, the position of the outlet
box can be made on the right side of the machine base, but it must
be specified when ordering.
3. Z2 series DC motors can work normally in forward or reverse
rotation.
4. The rotation direction of Z2 series generators and voltage
regulating generators is regarded as counterclockwise from the
shaft extension end. According to the requirements of use, it can
also be made into clockwise rotation generators or voltage
regulating generators, but it should be noted when ordering.
bright.
5. Z2 series generators and voltage regulating generators can be
supplied as a complete set of generator sets matched with Y series
three-phase asynchronous motors according to the order
requirements.
6. The rated power of the voltage regulating generator is the power
at the average voltage (135 volts for 110/160 volts, and 270 volts
for 220/320 volts). When the voltage is higher than the average
voltage, its output power is not greater than the rated power.
Power, when the voltage is lower than the average voltage, its
output current is not greater than the rated current.
7. The DC generator or the DC voltage regulating generator is only
one type of horizontal type with feet on the base.
3. Model description
Z means "direct" flow, 2 means the second national finalized
design, the number after the horizontal line means the frame number
and the length of the iron core. In -112, 11 represents the 11th
frame, and 2 represents the long iron core.
4. Product performance
1. The armature voltage of the basic series of DC motors is 1110V;
there are two types of 220V, and the rated speed is 3000r/min,
1500r/min, 1000r/min, 750r/min, and 600r/min.
2. The rated voltage of the basic series of DC generators is 115V
and 230V, and the rated speed is 2850r/min, 1450r/min; nfn960r/min,
a total of 3 types.
3. The rated voltage of the basic series of DC generators is
110V/160V and 220V/320V, and the rated speed is 2850r/min and
1450r/min.
4. In addition to the above three basic series motors, the armature
voltage is 180V, the technical data is shown in Table 6, and the
armature voltage is 440V.
5. In addition to the data listed above, any motor of any
specification can be derived into other levels of voltage (but not
exceeding the maximum voltage allowed by the specification) and
corresponding power and speed, but should be negotiated separately.
