Z4 series DC motor

Description and application

The Z4 series DC motor(center height: 100mm-450mm)can be used in various industrial departments. Such as rolling mill, 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 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 20r/min.

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 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, light weight, large output, high efficiency and reliability, being able to match the current international advanced level.

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.

The motors can be lastingly operated from fully controlled 3 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 data, should be inserted in the armature circuit to suppress ripple current.

Electrical performance

Ratings are applicable to S1 continuous operating under the following conditions:

Altitude above sea level: < 1000m

Temperature of coolant: < 40℃

Operating according to the technical data sheet.

Insulation Class: F

Z4 series DC electric motor
Power range:1.5kW--600kW

Standard Rated voltage:160V/440V/ etc
Base Speed:3000/1500/1000/750/600/500/400/300/200rmin (9 types)

Exciting method: separated excitation
Nominal Field voltage:180V. Other excitation voltages are also acceptable on request.

According to the general condition and needs of customers, except the above standard specifications, Ot also can be derived for other power, armature voltage and excitation voltage.

From the drive end(Non-commutator position), The standard terminal box is on the right position of the motor frame. For the request by customer, the terminal box can be made on the opposite position. Also the shaft can be made as double shaft end. The rotor shaft's rotation direction is counter clock-wise viewed from the position of commutator. The driving mode is flexible coupling connection, also can be use for the driving mode have certain radial force(such as belt drive or gear drive), It's allowable radial force should not exceed the value of graph.(see attached B)

3. Accessories for electric motor

According to customer's request, the motor can be designed to allocate for tacho generator, pulse generator, centrifugal switch, arrester brake and so on.

Note: the specification, power and weak-magnet speed range is only for reference, For the refresh of new technologies, new materials, the data of the catalog will be changed accordingly.simo_kyle#foxmail.com
