Brusheless DC Motor 200kw

Product Description

Brusheless dc motor 200kw

Series brushless DC motor is newly developed products of our works. The products are found wide use for prime mover in various, sucb as mill auxilinry in merallurgical induetry, metal cutting machine-tool, paper making, print, textile, printing and dyeing, cement-making,plastic extruding machine, etc. Outline and mounting dimensions of the motors comply with IEC72 Standard, except for the axial distance between the mounting holes (dimension B). Performance and technical requirements of the motors can be checked in accordance with IEC34-1 Standard of the International Electro technical Commission, or DIN57530 Norm of the Deutsche Industries-Norm. The motors are class F insulated, with reliable insulating construction and impregnating process, cnsuring stable dielectric performance and excellent heat dissipation. The motors possess the features of small size, good performance, light weight, large output, high efficiency and reliability, being able to match the current international advanced level. The motors can be lastingly operated form fully controlled three-phase bridge without a smoothing reactor. Motors for 160V may be operated on single-phase bridge thyristor. In that case, a smoothing reactor, whose inductance is specified in the relevant technical date, should be inserted in the armature circult to suppres ripple current.

Structure:

1.Protection, mounting and type of construction: a. Type of protection of the whole series: IP21S b. Mounting modes comply with the State Standard GB/T997 stipulated as follows:

2.Methods of Cooling: Modes of cooling for all the motors are separate cooling, force ventilated. Cooling by frame radially mounted, separately powered ventilating fan, and attached with an air filter. Modes of cooling for motors may be made into three types, namely IC06, IC17 and IC37. a.For Z4-100-Z4-160, the blower is mounted on the non-drive side. b.For Z4-180-Z4-450, the blower is mounted on the drive side.

    All the ventilating fan motors are of three phase, two pole, 380V. Motors with the following five methods of cooling can also be ordered, but prior consultations are needed. a. Frame size 100 up to 250 may be made into the totally enclosed, frame cooled motor (IC410). b. Frame size 160 up to 250 may be made into the separately ventilated motor with blower mounted on its non-drive side (IC05). c. Frame size 100 up to 200 may be made into the self cooled open motor with its own fan mounted on the shaft (IC01). d. Frame size 160 up to 355 may be made into totally enclosed motor with internal cooling air circulation by independent air-air heat exchanger mounted on it (IC666). e. Frame size 160 up to 450 may be made into totally enclosed motor with independent air-water heat exchanger mounted on it (IC86W). 3. Standard terminal box mounting is the right hand side seen form the drive end of the motor. As an alternative, mounting at the top or on the lefthand side is possible on request. 4. Motors if needed, can be fitted with tachogenerator or other accessories at the non-drive end. 5. Motors, when directly coupled, must use elastic or flexible couplings. The drive and driven units must be aligned with the utmost care. Radial forces acting on the shaft-extensions (belt or pinion drive) must not exceed the values given in the diagrams in the following pages (see Appendix2). Motors are of compact structure, elegant appearance, spacious terminal box, easy wiring, servicing and maintenance.
