1. The methods and protection degree of the motor
a) The method of cooling of the motor is separately-cooled, according to GB/T1993 "Method of cooling of rotating electrical machinery", there are IC06, IC17, IC37, IC86W. Standard entrance of cooling air is at the end of the main transmission(not the commutator side). The protection class of the motor can be divided into IP23 and IP44 according to the GB/T4942.1 and IEC34-5. If the user needs other method of cooling and defend class, it can be negotiated.
b) the relation between the method of cooling and the protection degree of the motor pls see
c) the cooling method, wind pressure, cooling water flux, motor power see: Table 2.
air-to-water heat exchanger
Wind pressure (whisht pressure)
Cooling water flux
2. The installation and the type of motor according to the GB/T997 "the structure and installation type of rotating electrical machinery", have IM1001(Horizontal bottom install, column biaxial) and IM1002 (Horizontal bottom install, column biaxial). If the user needs other kinds of installation structure, it must be negotiated.
3. The position of terminal box on standard motor is on the right side when seeing from the main drive end. It can also be installed on the left side, but it must be written in the order contract.
4. The motor using rolling bearing, nonstop adding oil structure.
5. The motor can be installed the following accessories at the user's option.
a) temperature detector component can be put into stator winding and bearing room of 2 side, and connect the outlet wire to the terminal box.
b) The non-drive party of the machine can equipped with tacho-generator, centrifugal starting switch, coder and others which build up the speed meter protecting device.
c) Heater for preventing condensation can be installed in the motor, but it must be written in the other contact
6. The air-to water heat exchanger is usually installed on the top of the motor. If the user wants to be installed on the side of the motor, the user must put forward it when ordering and settle the assistant upholder by the user himself.
7. The cooler equipped with wind pressure switch, temperature controller, heater for preventing condensation and pther protect device.
1. The motor type, power, voltage, running speed, excitation type, cooling type, number of output draft, position of outlet box, etc. Must be written when ordering.
2. Pls give clear indication of the accessory's type, specification and number installed on the motor when ordering.
3. If the environment of using is special, humid torrid zone type motor is needed pls write "H" after the original type.
4. If you have some special requirement of the specification and technical requirement which is not listed in the booklet, pls contact us.
