Mounting Dimensions


one. Mounting and Type of development

Mounting modes comply with the State CZPT GB/T997 stipulated as follows:

2. Defense and Cooling Technique.

The basic cooling technique of motor is IC06, It indicates it have a blower for ventilate, also it can be produced for IC17, It signifies use pipe as the cold air inlet, the air outlet is shutter construction. Also it can be produced for IC37, it indicates the cold air’s inlet and outlet both use pipe. And it truly is have a lot of deriving form, this sort of as self-ventilation, axial stream supporter variety, enclosed kind, air-air cooler type, etc. The request for the air flow, blast strain, electricity of the air blower, and so forth of diverse body motor please see complex information sheet 1. The safety degree of entire sequence Z4 motor reaches IP21S

a. For Z4-100 – Z4-a hundred and sixty, The blower is mounted on the non-travel side.

b. For Z4-180 – Z4-450, The blower is mounted on the travel aspect.

c. The necessary cooling air volume, air force and admirer motor capability are proven underneath:(Table one)

*All the ventilating enthusiast motors are 3 period, two pole, 380V.

Motors with the adhering to 5 approaches of cooling can also be ordered, but prior consultations are needed.

a. Frame dimensions one hundred up to 250 might be created into the absolutely enclosed, body cooled motor(IC410).

b. Body dimension one hundred eighty up to 250 might be created into the independently ventilated motor with blower mounted on its non-generate side(IC05).

c. Frame dimensions 100 up to 200 may possibly be created into self-cooled open motor with its own supporter mounted on the shaft(IC01).

d. Frame measurement a hundred and sixty up to 355 could be created into totally enclosed motor with inner cooling air circulation by impartial air-air heat exchanger mounted on it(IC666).

e. Body measurement a hundred and sixty up to 450 might be made into entirely enclosed motor with independent air-h2o heat exchanger mounted on it(IC86W).


From the push end(Non-commutator situation), The regular terminal box is on the correct place of the motor frame. For the ask for by customer, the terminal box can be made on the opposite situation. Also the shaft can be created as double shaft end. The rotor shaft’s rotation direction is counter clock-sensible considered from the position of commutator. The driving mode is adaptable coupling relationship, also can be use for the driving manner have particular radial force(such as belt drive or gear drive), It truly is allowable radial power should not exceed the value of graph.(see connected B)


3. Equipment for electrical motor

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

Notice: the specification, energy and weak-magnet velocity variety is only for reference, For the refresh of new technologies, new resources, the info of the catalog will be altered accordingly.


CZPTal efficiency

1, technical information need to be employed according to the pursuing knowledge work conditions                  

A. altitude does not exceed 1000m,
B. encompassing air temperature is not much more than 40 ° c,
C. function atmosphere ought to not incorporate acid and alkaline or other to contact with insulation   influence of fuel.
D. motor for continuous duty (S1),
E. motor armature loop and excitation circuitry by static electricity, rectifying electricity supply by dc generators.

F. the sequence motor performance with GB/T755 the simple technological innovation of motor.
two, motor 160V rated voltage is common, 440V. According to the specific situations can derive   220V and 400V or other voltage.
three, motor rated velocity 3,000, fifteen, 10, 750, 6, 5, four, three, 200r/min of 9.
To reduce the armature voltage constant torque manage, decrease excitation consistent power voltage for speed. Velocity assortment of complex knowledge desk saw.

In the subsequent with rated voltage regulating velocity is continual torque. It is no less than the bare minimum pace regulation 20r/min, still can preserve the rated velocity, torque.

4, Separate excitation is the standard excitation type of the motors. Nominal subject voltage: 180V. Other excitation voltages are also satisfactory on ask for. 
Forced excitation is allowed with the voltage of much less than 500v. When a motor is generally running, its excitation current must not be increased than the rated excitation current.

To ensure the trustworthiness of the insulation of excitation program, disconnect excitation circuitry on a area winding resistance, release ends in parallel to stop self-induction prospective. In its price normal excitation voltage is about 7 occasions the area winding resistance (cold state). Although the field voltage is increased than nominal voltage, the benefit of shunt resistance could be reduced than seven moments subject resistance, otherwise larger than seven times.
5, For frame dimensions Z4-315, Z4-355,Z4-400, and Z4-450, compensating windings are supplied. For body dimensions Z4-250 and Z4-280, the motors are feasible with a compensating winding way too.

six, A marked earthing terminal is provided for the motors.

7, The efficiency listed in the knowledge sheet are for rated output, voltage and speed , and consist of excitation losses, excluding that of separate ventilating enthusiasts.  

Get Recognize

one. Pls examine our items catalog and confirm the motor kind and specification prior to area purchase,  and type variety as feasible as standard specs shown in catalog. For motor  body dimensions, energy, voltage, velocity, interesting technique, exciting voltage and mounting sort, ought to be mentioned clear in product sales contract. Such as Z4-one hundred eighty-31, 37KW, 440V, 1000r/min, separated excitation 180v, horizontal mounting with toes or IMB3.

2. Some specific demands these kinds of as : double shaft conclude, terminal box place are mounting in the opposite way, counter clock-clever rotation have to be mentioned evidently in the deal.

3. If the buyer need kind, specification are not checklist in the catolog, or for other specific prerequisite,  the agreement or the pre-creation arrangement ought to be signed following both party’s discussion and arrangement

four. All the motors , Apart from the shaft extension important, all the components are not in the extent of supply, If the accessories or spare parts are requested,  such as the brush, brush holder, and so on,  pls observe the name, specification and portions of the accessories in the deal.

five. For particular setting operating condition, motor would be utilized in humid and sizzling regions,  pls label TH in the origin type.
