Z4 Series Direct Current Motor Description

Z4 Series Medium Size DC machine motor is newly developed product of our works. 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, plastic extruding 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 DIN57530 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 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 armature circuit to suppress ripple current.

The Z4-series DC motors has more advantage than Z2 and Z3 series. It is not only available for DC power-supply set, and more suitable for stationary power supply rectifier. It have small moment of inertia, preferable dynamic performances, also it can withstand 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 reach the international advanced level.

Z4 Series Direct Current Motor Configuration

1.Protection, mounting and type of construction

A.Types of protection of the whole series; Ip21S

B.Mounting modes comply with the State Standard GB/T997 stipulated as follows.

2.Methode of Cooling:

Modes of cooling for all the motors are separate cooling, force ventilated. Cooling by frame radially fan, and attached an air filter. Modes of cooling for motors may be made into three types, namely IC-06, IC-17 and IC-37.

A. For Z4-100~Z4-160, the blower is mounted on the drive side.

B. For Z4-180~Z4-450, the blower is mounted on the drive side

Z4 Series Direct Current MotorElectrical machinery performance:

1.Data listed in the technical data sheet should be employed under the following conditions;
a.Aitirude above sea level maximal 1,000m;
b.Cooling air remperature maximal 40℃;
c.Ambient conditions for motors should be free from acidic, alkali fumes or other aggressive gasea which corrode insulation.
d.Duty: Continuous (SI);
e.Armature and field circuits for motors may be either operated on static thyrisier controlled supplies, or from d-c generator;
f.Performances of motors all comply with State Standard GB755. Fundamental technical rules for electrical machines.
2.Standard rated voltage: 160V or 440V, Values for 220V, 400V, and 660V or other voltage may be derived on request.
3.Rated speed:
3000,1500,1000,750,600,500,400,300 and 200 r/min, totally nine grades. Decrease armature voltage to make speed regulating under constant torque, lowering down field voltage to make speed regulating at constant output. Speed regulating range: see technical date . The torque can be remained constant by reducing speed via armature voltage weakening below raced value. It is stipulated that armature speed range can be down to the lowest 20 r/min at constant torque and stable running.
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 the voltage of less than 500V. When a motors is normally running, its excitation current must not be higher than rated excitation current. To assure the reliability of insulation of excitation system, the motor must be protected against self induced voltages by a release resistor connected in parallel with the excitation circult of the motor is interrupted. At rated field voltage the value of shunt resistor is about seven times filed 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 size Z4-315, Z4-355, Z4-400 and Z4-450, compensating windings are provided. For frame size Z4-250 and Z4-280 the motors are feasible with a compensating winding too.
6.A marked earthing terminal is provided forth motors.
7.The efficiencies listed in the date sheet are for rated output, voltage and speed, and include excitation lose, exciuding that of separate ventilating fans.
