Technical Data
Mounting Dimensions
Product Description
The Z4 series DC motor(center height: 100mm-450mm)can be used in various industrial departments. Such as rolling mills, metal cutting machine tool, papermaking, dyeing and weaving, printing industry, cement factory, plastic extrusion equipment, and so on. They are suitable in areas where wide-range speed adjustment is needed and the overloading capacity does not exceed 1.6 times of rated torque. Upward speed adjustment by the constant power weak field method can reach 1.0-3.0 times of rated speed. Downward speed adjustment by constant torque and decreased mature voltage method can reach 20r/min.
Outline and mounting dimensions of the motors comply with the IEC72 standard, except for the axial distance between the mounting holes(dimension B).
Performance and technical requirements of the motors can be checked in accordance with the IEC34-1 Standard of the International Electro-Technical Commission, or DIN57530 Norms of the Deutsche Industries-Norm.
The motors are class F insulated, with reliable insulating construction and impregnating process, ensuring stable dielectric performance and excellent heat dissipation.
The motors possess the features of small size, good performance, lightweight, large output, high efficiency, and reliability, being able to match the current international advanced level.
The Z4-series DC motors have more advantages than Z2 and Z3 series. It is not only available for DC power supply sets, and is more suitable for stationary power supply rectifiers. It has a small moment of inertia, and preferable dynamic performance, also it can withstand a higher load change rate. It is especially suitable for the control system which needs smooth speed variation, high efficiency, automatic steady speed, and reaction sensitivity. It is reaching the international advanced level.
The motors can be lastingly operated from the fully controlled 3-phase bridge without a smoothing reactor. Motors for 160V may be operated on a single-phase bridge thyristor. In that case, a smoothing reactor, whose inductance is specified in the relevant technical data, should be inserted in the armature circuit to suppress ripple current.
Construction
1. Mounting and Type of construction
Mounting modes comply with the State Standard GB/T997 stipulated as follows:
2. Protection and Cooling Method.
The basic cooling method of the motor is IC06, It means it has a blower for ventilating, also it can be made for IC17, Which means using the pipe as the cold air inlet, and the air outlet is a shutter structure. Also, it can be made for IC37, which means the cold air's inlet and outlet both use the pipe. And it has many deriving forms, such as self-ventilation, axial flow fan type, enclosed type, air-air cooler type, etc. The request for the airflow, blast pressure, power of the air blower, etc of different frame motors please see technical data sheet 1. The protection degree of the whole series Z4 motor reaches IP21S
a. For Z4-100 - Z4-160, The blower is mounted on the non-drive side.
b. For Z4-180 - Z4-450, The blower is mounted on the drive side.
c. The required cooling air volume, air pressure, and fan motor capacity are shown below:(Table 1))
*All the ventilating fan motors are three phases, two poles, 380V.
Motors with the following 5 methods of cooling can also be ordered, but prior consultations are needed.
a. Frame size 100 up to 250 may be made into the totally enclosed, frame cooled motor(IC410).
b. Frame size 180 up to 250 may be made into the separately ventilated motor with a blower mounted on its non-drive side(IC05).
c. Frame size 100 up to 200 may be made into the self-cooled open motor with its own fan mounted on the shaft(IC01).
d. Frame size 160 up to 355 may be made into the totally enclosed motor with internal cooling air circulation by an independent air-air heat exchanger mounted on it(IC666).
e. Frame size 160 up to 450 may be made into the totally enclosed motor with an independent air-water heat exchanger mounted on it(IC86W).
From the drive end(Non-commutator position), The standard terminal box is in the right position of the motor frame. For the request by the customer, the terminal box can be made in the opposite position. Also, the shaft can be made as a double shaft end. The rotor shaft's rotation direction is counter clock-wise viewed from the position of the commutator. The driving mode is a flexible coupling connection, and also can be used for the driving mode to have a certain radial force(such as belt drive or gear drive), It's allowable radial force should not exceed the value of the graph.(see attached B)
3. Accessories for electric motor
According to the customer's request, the motor can be designed to allocate for the tacho generator, pulse generator, centrifugal switch, arrester brake, and so on.
Note: the specification, power, and weak-magnet speed range are only for reference, For the refresh of new technologies, and new materials, the data of the catalog will be changed accordingly.
Electrical performance
1, technical data should be used according to the following data work conditions
A. altitude does not exceed 1000m,
B. surrounding air temperature is not more than 40 ° c,
C. work environment should not contain acid and alkaline or other to touch with insulation effect of the gas.
D. motor for continuous duty (S1),
E. motor armature loop and excitation circuitry by static electricity, rectifying power supply by dc generators.
F. the series motor performance with GB/T755 the basic technology of motor.
2, motor 160V rated voltage is standard, 440V. According to the specific conditions can derive 220V and 400V or other voltage.
3, motor rated speed 3,000, 15, 10, 750, 6, 5, 4, 3, 200r/min of nine.
To reduce the armature voltage constant torque control, reduce excitation constant power voltage for speed. Speed range of technical data table saw.
In the following with rated voltage regulating speed is constant torque. It is no less than the minimum speed regulation of 20r/min, and still can maintain the rated speed, and torque.
4, Separate excitation is the basic excitation type of the motors. Nominal field voltage: 180V. Other excitation voltages are also acceptable on request.
Forced excitation is allowed with a voltage of less than 500v. When a motor is normally running, its excitation current must not be higher than the rated excitation current.
To ensure the reliability of the insulation of the excitation system, disconnect excitation circuitry on a field winding resistance, and release ends in parallel to prevent self-induction potential. In its value, the standard excitation voltage is about seven times the field winding resistance (cold state). While the field voltage is higher than nominal voltage, the value of shunt resistance may be lower than seven times field resistance, otherwise higher than seven times.
5, For frame sizes Z4-315, Z4-355, Z4-400, and Z4-450, compensating windings are provided. For frame sizes Z4-250 and Z4-280, the motors are feasible with a compensating winding too.
6, A marked earthing terminal is provided for the motors.
7, The efficiency listed in the data-sheet is for rated output, voltage, and speed, and includes excitation losses, excluding that of separate ventilating fans.
