ZSN4 400v dc motor is brush dc motor, its frame starts from 355mm to 710mm, which is newly designed medium-sized DC motor after Z4 series DC motor. It can be widely used in metallurgical industry, rolling mills, metal cutting machine tools, paper, dyeing, printing. We export it to South East Asia, Middle East, Europe more than 20 years. With high efficiency, energy saving, reliable quality, our products are high praised by clients at home and abroad.
This series of ZSN4 400v dc motor adopts advanced design, the stator base adopts polygonal lamination structure, which effectively makes full use of space, and has the advantages of small size, light weight, and good performance. The stator poles and armature core are made of laminated cold-rolled silicon steel plates, which have good magnetic permeability.
The entire stator and rotor are treated with solvent-free vacuum pressure impregnation (VPI), which makes the winding have good moisture resistance and mechanical strength, and excellent insulation and thermal conductivity. This series of motors use rolling bearings, non-stop refueling structure, which is divided into 400v dc motor and 440v dc motor.
The power range of this kind dc motor is from 1.5kW to 550kW, the rated speed is 3000, 1500, 1000, the excitation method is separate excitation, the excitation voltage is 180V, and the motor’s rating is continuous working and continuous rating. The altitude does not exceed 1000m and the temperature does not exceed 40 ℃, using F-class insulation.
