  • Blower motors are 3 section,380VAC,50HZ.

2. Motor mounting type
GB/T997 “Symbols for Varieties of CZPT and Mounting Arrangement of Rotating CZPTal CZPT” defines two mounting kinds of IM1001 (horizontal motor,  single cylindrical shaft extension) and IM1002 (horizontal motor with feet, double cylindrical shaft extension). If clientele are fascinated in other set up sort, seek advice from the producer.

three.CZPT place of the terminal box is at the appropriate aspect of the motor from the view of DE. If the terminal box wants to be set at the still left facet of the motor, shopper shall specify in the deal.

4. Rolling bearing, and non-quit refuel device.

5. Offered auxiliary units (need to specify in agreement)

a)Temperature sensor can be fastened at stator winding and bearing chamber on every single conclude, and its out-top cable need to be connected to terminal box.

b)Velocity measuring and defending device consisting motor-screening units, centrifugal switch, encoder etc can be fixed on the NDE facet.

c)Heater can be installed

6.Air/water cooler is generally fastened on the higher facet of the motor. If the cooler is requested to be mounted at sides of the motor, client want to specify in the buy or contract. Apart from, clientele is accountable for the auxiliary help of the cooler.

7.Cooler can be put in with LFAS, temperature controller and heater.

Motor Overall performance   

1. CZPT Info:

a)Altitude not exceeds 1000m.

b)Air temperature at inlet of cooling blower shall be no greater than 40ºC inlet drinking water temperature shall be no higher than 32ºC.

c)Correct cooling method and protection grade need to be picked to preserve the interior elements thoroughly clean if the motor want to be put in in harsh environment. Consult the producer for depth details.

d)A few stage bridge rectifier electrical power supply, non-external flat wave reactor, direct-electricity generator are CZPT.

e)Conform to GB755 “Rotating electrical machines-Ranking and overall performance”,IEC60034-1 “Rotating electrical devices-Ranking and performance” and JB/T9577 “CZPT specification for Z collection DC motor”

two. Rated voltage 440V,550V,660,750V. Seek the advice of the producer if the consumers are interested in motor of other voltage.
three. The motor is individual-exciting variety whose thrilling voltage is 220V. Check with the producer for derived motor of other voltage. Forced thrilling whose voltage no far more than 500V is allowed, but the fascinating present cannot be increased than rated price during procedure.
