Z4 Series DC Motor

The Z4 series DC motor(center height: 100 mm-450 mm)can be used in various industrial departments. Such as rolling mill, metal cutting machine tool, paper making. 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 constant power weak field method can reach 1.0-3.0 times of rated speed. Downward speed adjustment by constant torque and decreased amature voltage method can reach 20rpm. Z4-355-32 450KW 45度 3

Model description:

The letter "B" stands for motor with compensating winding. Only applicable to Z4-250 and Z4-280.

The digit 1,2 for short and long endshield.

As regards frame size 112, the first digit means number of poles and the second digit for core length.

The letter "Z" for dc motor; the digit "4" for ordinal number of the forth series design.

Protection and Cooling Method.

1. protection of the whole series is IP21S.

2. Modes of cooling for all the motors are separate cooling and forced ventilated. Cooling fans are radially mounted, separtely powered and attached with an air filter. Modes of cooling for motors can be made into types of IC06, IC17 and IC37.

3. Location of the cooling fan.

a. For frame 100mm to frame 160mm, the cooling fan is mounted on the non-drive side.

b. For frame 180mm to frame 450mm, the cooling fan is mounted on the drive side.

c. The required cooling air volume, air pressue and fan motor output are shown below (Table 1):

Z4-450	9000	1800	7.5

Tips: All cooling fan motors are 2 pole 380v three phase asynchronous motor.

Location of the terminal box:

Standard terminal box is mounted on the right hand side seen from the drive end of the motor.
Terminal box as request can be mounted on the top or on the lefthand side.

Order Notice.

1. Please check our products catalog and confirm the motor type and specification before place order, and type selection as possible as
standard specifications shown in catalog.
2. For motor frame size, power, voltage, speed, exciting method, exciting voltage and mounting form, should be mentioned clear in
sales contract. Such as Z4-180-31, 37KW, 440V, 1000rpm, separated excitation 180V, horizontal mounting with feet or IMB3.

Some special requirements such as : double shaft end, terminal box position are mounting in the opposite way, counter clock-wise

rotation must be mentioned clearly in the contract.

3. If the humid-tropical type is required, please mark "TH" behind the original type model.
