dc motor brushes

dc motor brushes   Z4 series dc motor brushes
widely used for sea port construction,
crane motor, sugar-making motor,
rolling motor mill   Series Z4 dc machines are newly developed products of our works. The products are found wide use for prime mover in various, such as mill auxiliary in metallurgical industry, metal cutting machine-tool, paper-making, print, textile, printing and dyeing, cement-making, plastic extruding machine etc.   1. Outline and mounting dimensions of the motors comply with IEC 72 standard, except for the axial distance between the mounting holes (Dimension B).   2. Performance and technical requirements of the motors can be checked in accordance with IEC 34-1 Standards of the International Electro Technical Commission, or DIN 57530 Norm of the Deutsche Industries-Norm.   3. The motors are class F insulated, with reliable insulating construction and impregnating process, ensure stable dielectric performance and excellent hear dissipation.   4. The motors possess the features of small size, good performance, light weight, large output, high efficiency and reliability, being able to mach the current international advanced level.   5. The motors can be lastingly operated form fully controlled three-phase bridge without a smoothing reactor. Motors for 160V maybe 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 circuit to suppress ripple current.   Features: 1. Technical Standards:   a. Continuous Duty: S1   b. Domestic Environmental Standard: GB/T 755 (Fundamental Technical Qualifications for motor) 2. Specifications:   a. Nominal Rated Voltage: 160V, 440V (220V, 440V, or other voltage available)   b. Nominal Field Voltage: 180V.   Company Exhibition
