Mounting Dimensions


1. Mounting and Type of building

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

two. Safety and Cooling Strategy.

The fundamental cooling method of motor is IC06, It indicates it have a blower for ventilate, also it can be made for IC17, It means use pipe as the cold air inlet, the air outlet is shutter composition. Also it can be manufactured for IC37, it signifies the cold air’s inlet and outlet both use pipe. And it really is have numerous deriving sort, this sort of as self-ventilation, axial circulation admirer sort, enclosed kind, air-air cooler kind, and so forth. The request for the air movement, blast stress, energy of the air blower, etc of distinct frame motor make sure you see complex data sheet 1. The security degree of complete collection Z4 motor reaches IP21S

a. For Z4-a hundred – Z4-160, The blower is mounted on the non-travel facet.

b. For Z4-a hundred and eighty – Z4-450, The blower is mounted on the generate aspect.

c. The essential cooling air volume, air force and supporter motor potential are revealed underneath:(Desk one)

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

Motors with the following 5 approaches of cooling can also be requested, but prior consultations are essential.

a. Body dimension 100 up to 250 may possibly be created into the completely enclosed, body cooled motor(IC410).

b. Frame size a hundred and eighty up to 250 may be made into the individually ventilated motor with blower mounted on its non-push side(IC05).

c. Frame dimension one hundred up to two hundred may be created into self-cooled open up motor with its own enthusiast mounted on the shaft(IC01).

d. Body size a hundred and sixty up to 355 may possibly be produced into absolutely enclosed motor with interior cooling air circulation by unbiased air-air warmth exchanger mounted on it(IC666).

e. Body dimensions 160 up to 450 could be made into entirely enclosed motor with independent air-water warmth exchanger mounted on it(IC86W).


From the travel finish(Non-commutator situation), The standard terminal box is on the correct position of the motor frame. For the ask for by buyer, the terminal box can be produced on the reverse placement. Also the shaft can be manufactured as double shaft stop. The rotor shaft’s rotation direction is counter clock-clever considered from the position of commutator. The driving method is flexible coupling link, also can be use for the driving manner have certain radial pressure(this kind of as belt drive or gear push), It really is allowable radial drive ought to not exceed the benefit of graph.(see attached B)


3. Add-ons for electrical motor

In accordance to customer’s request, the motor can be made to allocate for tacho generator, pulse generator, centrifugal switch, arrester brake and so on.

Be aware: the specification, electrical power and weak-magnet velocity assortment is only for reference, For the refresh of new technologies, new resources, the knowledge of the catalog will be changed accordingly.


CZPTal functionality

one, technological info should be used in accordance to the following knowledge perform conditions                  

A. altitude does not exceed 1000m,
B. encompassing air temperature is not much more than 40 ° c,
C. work surroundings ought to not have acid and alkaline or other to contact with insulation   effect of gas.
D. motor for continuous obligation (S1),
E. motor armature loop and excitation circuitry by static electricity, rectifying electrical power provide by dc turbines.

F. the sequence motor functionality with GB/T755 the simple technology of motor.
2, motor 160V rated voltage is normal, 440V. According to the distinct problems can derive   220V and 400V or other voltage.
3, motor rated speed 3,000, 15, ten, 750, six, five, 4, 3, 200r/min of 9.
To reduce the armature voltage consistent torque management, minimize excitation consistent electricity voltage for speed. Pace assortment of technological info desk observed.

In the following with rated voltage regulating pace is continual torque. It is no less than the minimum speed regulation 20r/min, nonetheless can preserve the rated speed, torque.

4, Separate excitation is the standard excitation variety of the motors. Nominal area voltage: 180V. Other excitation voltages are also satisfactory on ask for. 
Pressured excitation is authorized with the voltage of considerably less than 500v. When a motor is usually working, its excitation recent should not be higher than the rated excitation recent.

To guarantee the trustworthiness of the insulation of excitation program, disconnect excitation circuitry on a discipline winding resistance, launch ends in parallel to avoid self-induction potential. In its benefit common excitation voltage is about 7 instances the subject winding resistance (cold condition). Whilst the field voltage is higher than nominal voltage, the benefit of shunt resistance could be lower than 7 times subject resistance, or else increased than 7 occasions.
5, For body size Z4-315, Z4-355,Z4-400, and Z4-450, compensating windings are presented. For frame size Z4-250 and Z4-280, the motors are possible with a compensating winding too.

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

seven, The efficiency listed in the knowledge sheet are for rated output, voltage and pace , and consist of excitation losses, excluding that of separate ventilating followers.  

Get Recognize

one. Pls check our items catalog and affirm the motor sort and specification ahead of place order,  and variety choice as attainable as standard technical specs proven in catalog. For motor  body size, energy, voltage, velocity, thrilling approach, exciting voltage and mounting form, must be pointed out very clear in revenue deal. This sort of as Z4-180-31, 37KW, 440V, 1000r/min, divided excitation 180v, horizontal mounting with feet or IMB3.

two. Some particular specifications such as : double shaft end, terminal box placement are mounting in the reverse way, counter clock-sensible rotation have to be described plainly in the contract.

three. If the consumer need kind, specification are not listing in the catolog, or for other particular prerequisite,  the agreement or the pre-generation arrangement should be signed right after equally party’s discussion and agreement

four. All the motors , Besides the shaft extension key, all the components are not in the extent of source, If the add-ons or spare components are requested,  this kind of as the brush, brush holder, and so forth,  pls note the name, specification and quantities of the accessories in the agreement.

5. For specific atmosphere functioning situation, motor would be used in humid and sizzling areas,  pls label TH in the origin variety.
