DC motor shelf Z4-180-41 Z4 series DC motor plant in Xi'an: Center Height 100 ~ 355mm is the People's Republic of China Machinery Industry Standard JB / T6316-92 "Z4 series DC motor technology" specified in the standard series of small DC motor ; center height 400 ~ 450mm beyond the standard series expansion for the Z4 DC motor; high center 500 ~ 710mm is my factory newly developed medium-sized DC motors. Z4 series motors can be widely used in metallurgical industry mills, metal-cutting machine tools, paper, dyeing, printing, cement, plastic extrusion machinery and other industrial sectors. Z4 series DC motors than Z2, Z3 series has more advantages, it is not only usable DC power supply unit more suitable for stationary rectifier power supply. And the moment of inertia is small, has good dynamic performance and can withstand high load rate of change, especially for applications that require smooth speed, high efficiency, auto-speed responsive control system, with the current international advanced the DC fixed motor continuous rating for continuous operation, at an altitude of no more than 1000m, ambient air temperature does not exceed 40 ℃ areas, the motor can be run according to technical data sheet data Rated. This series motors are Class F insulation. Z4 series Z4132-1 18.5KW 440V DC motor cooling method and structure, installation forms IC06: comes with external ventilation blower; ICl7: cooling air inlet for the pipe, the exhaust outlet for blinds; IC37: that both cooling air inlet duct ; IC611: fully enclosed with air / air cooler; ICW37A86: fully enclosed with air / water cooler. And a variety of derivative forms, such as self-ventilated, with axial wind models, closed, air / air cooler type. Each frame size motors required cooling air flow, pressure, and fan motor power and other data in Table 1. Entire Z4 series motor enclosure protection rating IP21S basic DC motor shelf Z4-180-41
