  1. The structure and characteristics of YPS series AC motor:
 
  • This series AC motors are specially developed to substitute Z series middle to large DC motor for driving rolling mills with IGBT converter. This AC motor runs at constant speed under basic speed range while it runs with constant power output above basic speed. The converter doesn’t have harmonic filter and drives the motor directly; The insulation of motor has been considered of the special requirement for converter power supply. 
  • The motor base is a square structure made of steel plate welded. The axial tendon and stator core are connected to form a stator radial mixed ventilation to achieve the purpose of narrowing the outer diameter and weight of the base.
  • After stamping with high -quality non -high -quality magnetic, low-lost ferrite cold -rolled silicon steel sheet, it is fixed with both ends and axial welding tuber. After painting, it is made of reliable welding in the seat seat;
  • The electronic coil adopts the dedicated high -performance flat copper wire winding system for variable frequency speed regulating motors. It fully considers the adverse effects of the inverter power supply system on the insulation of the motor winding, and appropriately enhances the winding to the ground insulation and inter -turning insulation. The main insulation materials are currently the most advanced low glue content mica. Due to the reduction of glue content, this kind of mica band has greatly increased the content of mica under the same insulation thickness, thereby increasing the insulation performance and moisture -resistant, impact and heat dissipation performance of the winding;
  • The rotor is composed of iron core and axis. The rotor guide strip is made of frequent welding in high -quality bronze rows. The shaft adopts high -quality 35CRMO alloy steel and is treated with heat treatment, with excellent mechanical properties, and can resist frequent overload and other impact loads;
  • The motor drive shaft generally uses a rolling bearings or end cover sliding bearing structure. Rolling bearing can choose high -quality wear -resistant imported SKF or FAG products. The non -load -end bearings take insulation measures and configure the grounding brush on the transmission side to prevent the damage of the bearings;
  • The motor can be equipped with rotating speed feedback elements such as encoder, speed sensor, etc., heater for damp prevention and thermal elements such as PT100, PTC, etc. The overload capacity of the motor satisfies: a. continuous operation with 1.15 times of rated loading under rated voltage and rate speed range; b. occasional operation with 2.5 times of loading(at rated basic speed), duration less than 15S.
  • The rotating components of the motor can withstand 1.2 times over speed for 2 minutes without harmful deformation and damages. The accuracy of rotor dynamic balance is no less than G2.5.
  • The motor is complied with GB10068 rotating motor vibration testing methods and limits;
  • The rotation direction of the motor can be in any direction, but it must not be connected to the power brake or reverse during the operation;
  • The design of the motor adopts measures to eliminate the noise produced by converter power and is complied with GB10069 rotating motor noise testing methods and limits;
