DC Motor (Z4 Series)
Features:1) Technical standards:a) Continuous duty: S1b) Domestic environmental standard: GB/T 755 (fundamental technicalqualifications for motors)2) Specifications:a) Nominal rated voltage: 160V, 440V (220V, 440V or other voltage available)b) Nominal field voltage: 180Vc) Rated speed (nine grades): 200rpm, 300rpm, 400rpm, 500rpm, 600rpm,750rpm, 1000rpm, 1500rpm, 3000rpm3) Operating ambients:a) Altitude: less than or equal to 1,000mb) Maximum cooling temperature: 40oCc) Free from acidic, alkali fumes or other irritant gas which could corrode insulatingmaterials4) Compensation windings available for Z4-315, Z4-355, Z4-400 and Z4-4505) Z4-250 and Z4-280 are also feasible with compensation windings6) Marked earthing terminals suppliedArmature and field circuits for motors may be either operated by static thyristorcontrolled supplies or DC generators. Torque can be maintained constant byreducing speed via weakening armature voltage below rated value. We assurethat the lowest armature speed range can be decreased to 20rpm by invariabletorque and stable running. Meanwhile, field voltage is reduced to weaken speedwith a steady output.These motors have separate excitations. In addition to the above listed nominalfield voltage, other kinds of excitation voltage are also acceptable according tocustomers` requirements.If voltage is less than 500V, forced excitation is allowed. When a motor is normallyoperating, the excitation current should be no higher than the rated excitationcurrent. To keep the insulating materials of the excitation system reliable,the motor must be protected against self-induced voltage by a resistor connectedin parallel with the field windings when the excitation circuits of the motor areinterrupted.At rated field voltage, the resistance value of a shunt resistor is about seven timesmore than field resistance at low temperature. While the field voltage is higherthan nominal value, the resistance value of a shunt resistor may be lowerthan seven times of field resistance.
