Product Specification

Product Description

Features: 1) Technical standards: A) Continuous duty: S1 B) Domestic environmental standard: GB/T **5 (fundamental technical qualifications for motors) 2) Specifications: A) Nominal rated voltage: **0V, **0V (**0V, **0V or other voltage available) B) Nominal field voltage: **0V C) Rated speed (nine grades): **0r/min, **0r/min, **0r/min, **0r/min, **0r/min, **0r/min, ***0r/min, ***0r/min, ***0r/min 3) Operating ambients: A) Altitude: Less than or equal to 1,**0m B) Maximum cooling temperature: *0oC C) Free from acidic, alkali fumes or other irritant gas which could corrode insulating materials 4) Compensation windings available for Z****5, Z****5, Z****0 and Z****0 5) Z****0 and Z****0 are also feasible with compensation windings 6) Marked earthing terminals supplied Armature and field circuits for motors may be either operated by static thyristor controlled supplies or DC generators. Torque can be maintained constant by reducing speed via weakening armature voltage below rated value. We assure that the lowest armature speed range can be decreased to *0r/min by invariable torque and stable running. Meanwhile, field voltage is reduced to weaken speed with a steady output. These motors have separate excitations. In addition to the above listed nominal field voltage, other kinds of excitation voltage are also acceptable according to customers' requirements. If voltage is less than **0V, forced excitation is allowed. When a motor is normally operating, the excitation current should be no higher than the rated excitation current. To keep the insulating materials of the excitation system reliable, the motor must be protected against self-induced voltage by a resistor connected in parallel with the field windings when the excitation circuits of the motor are interrupted. At rated field voltage, the resistance value of a shunt resistor is about seven times more than field resistance at low temperature. While the field voltage is higher than
