  • Blower motors are three phase,380VAC,50HZ.
2. Motor mounting type
GB/T997 "Symbols for Types of Construction and Mounting Arrangement of Rotating Electrical Machinery" defines 2 mounting types of IM1001 (horizontal motor,  single cylindrical shaft extension) and IM1002 (horizontal motor with feet, double cylindrical shaft extension). If clients are interested in other installation type, consult the producer.
 
3.Standard position of the terminal box is at the right side of the motor from the view of DE. If the terminal box needs to be fixed at the left side of the motor, client shall specify in the contract.
 
4. Rolling bearing, and non-stop refuel device.

5. Available auxiliary devices (must specify in contract)
a)Temperature sensor can be fixed at stator winding and bearing chamber on each end, and its out-leading cable need to be connected to terminal box.
b)Speed measuring and protecting device consisting motor-testing devices, centrifugal switch, encoder etc can be fixed on the NDE side.
c)Heater can be installed
 
6.Air/water cooler is usually fixed on the upper side of the motor. If the cooler is requested to be mounted at sides of the motor, client need to specify in the order or contract. Besides, clients is responsible for the auxiliary support of the cooler.
7.Cooler can be installed with LFAS, temperature controller and heater.
   
Motor Performance    
                                                    
1. Technical Data:
a)Altitude not exceeds 1000m.
b)Air temperature at inlet of cooling blower shall be no higher than 40ºC; inlet water temperature shall be no higher than 32ºC.
c)Correct cooling method and protection grade should be chosen to keep the internal parts clean if the motor need to be installed in harsh environment. Consult the producer for detail information.
d)Three phase bridge rectifier power supply, non-external flat wave reactor, direct-power generator are available.
e)Conform to GB755 "Rotating electrical machines-Rating and performance",IEC60034-1 "Rotating electrical machines-Rating and performance" and JB/T9577 "Technical specification for Z series DC motor"
 
2. Rated voltage 440V , 550V , 660 , 750V. Consult the producer if the clients are interested in motor of other voltage.
3. The motor is separate-exciting type whose exciting voltage is 220V. Consult the producer for derived motor of other voltage. Forced exciting whose voltage no more than 500V is allowed, but the exciting current can't be higher than rated value during operation.

4. Short duration overload capacity

d): TypeII(B) DC motor can bear the following continuous load:
In rated voltage and rated speed the motor can work with 115% rated output power load. Under this circumstance, the motor's performance may differ from the one under rating condition due to its high temperature rise.
In rated voltage and rated speed, the motor can work with 125% rated output power load for 2 hours after that the motor operates continuously with rated load for a while. Under this circumstance, the motor's performance may differ from the one under rating condition due to its high temperature rise.
e): Type II (B) DC motor, when operating by rating speed, the motor allows to operate with 2.5 times its rated load for short time no longer than 15s(Consult manufacture and when they permit)
5. Current changing rate
The maximum current changing rate (di / dt) the motor can bear is 250 times of rated current.
