Series Z4 DC machines are newly developed products of our factory. The products are

found wide use for prime mover in various, such as mill auxiliary in metallurgical

industry, metal cutting machine-tool, paper making, print, textile, printing

and dyeing, cement-making, plasticextruding machine, etc.

Outline and mounting dimensions of the motors comply with 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 IEC34-1 Standard of the International Electro technical Commission, or DIN57350

Norm 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, light weight, large

output, high efficiency and reliability, being able to match the current international

advanced level.The motors can be lastingly operated form fully controlled three-phase bridge without

a smoothing reactor. Motors for 160V may be operated on single-phase bridge

thyristor. In that case, a smoothing reactor, whose inductance is specified in

the relevant technical date, should be inserted in the reactor to suppress ripple

current.

Features: 1) Technical standards: A) Continuous duty: S1 B) Domestic environmental standard: GB/T 755 (fundamental technical qualifications

for motors)

2) Specifications: A) Nominal rated voltage: 160V, 440V (220V, 440V or other voltage available) B) Nominal field voltage: 180V C) Rated speed (nine grades): 200rpm, 300rpm, 400rpm, 500rpm, 600rpm, 750rpm, 1000rpm,

1500rpm, 3000rpm

3) Operating ambients: A) Altitude: Less than or equal to 1, 000m B) Maximum cooling temperature: 40oC C) Free from acidic, alkali fumes or other irritant gas which could corrode insulating

materials

4) Compensation windings available for Z4-315, Z4-355, Z4-400 and Z4-450 5) Z4-250 and Z4-280 are also feasible with compensation windings 6) Marked earthing terminals supplied Armature and field circuits for motors may be either operated by static thyristor

controlled supplies or DC generators. Torque can be maintained constant by reducing

speed via weakening armature voltage below rated value. We assure that the

lowest armature speed range can be decreased to 20rpm by invariable torque and stable

running. Meanwhile, field voltage is reduced to weaken speed with a steady

output.

These motors have separate excitations. In addition to the above listed nominal field

voltage, other kinds of excitation voltage are also acceptable according tocustomers'

requirements.

If voltage is less than 500V, forced excitation is allowed. When a motor is normally

operating, the excitation current should be no higher than the rated excitation

current. To keep the insulating materials of the excitation system reliable,

the motor must be protected against self-induced voltage by a resistor connected

in parallel with the field windings when the excitation circuits of the motor

are interrupted.

At rated field voltage, the resistance value of a shunt resistor is about seven times

more than field resistance at low temperature. While the field voltage is higher

than nominal value, the resistance value of a shunt resistor may be lower.
