Hotsell bottom price Z4 brushless dc motor high voltage high speed motor

Z4 high voltage dc high speed motor performance:

1.Data listed in the technical data sheet should be employed under the following conditions; a.Aitirude above sea level maximal 1,000m; b.Cooling air remperature maximal 40°C; c.Ambient conditions for motors should be free from acidic, alkali fumes or other aggressive gasea which corrode insulation. d.Duty: Continuous (SI); e.Armature and field circuits for motors may be either operated on static thyrisier controlled supplies, or from d-c generator; f.Performances of motors all comply with State Standard GB755. Fundamental technical rules for electrical machines. 2.Standard rated voltage: 160V or 440V, Values for 220V, 400V, and 660V or other voltage may be derived on request. 3.Rated speed: 3000,1500,1000,750,600,500,400,300 and 200 r/min, totally nine grades. Decrease armature voltage to make speed regulating under constant torque, lowering down field voltage to make speed regulating at constant output. Speed regulating range: see technical date . The torque can be remained constant by reducing speed via armature voltage weakening below raced value. It is stipulated that armature speed range can be down to the lowest 20 r/min at constant torque and stable running. 4. Separate excitation is the basic excitation type of the motors. Nominal field voltage: 180V. Other excitation voltages are also acceptable on request. Forced excitation is allowed with the voltage of less than 500V. When a motors is normally running, its excitation current must not be higher than rated excitation current. To assure the reliability of insulation of excitation system, the motor must be protected against self induced voltages by a release resistor connected in parallel with the excitation circult of the motor is interrupted. At rated field voltage the value of shunt resistor is about seven times filed winding resistance (cold state). While the field voltage is higher than nominal voltage, the value of shunt resistance may be lower than seven times field resistance, otherwise higher than seven times. 5.For frame size Z4-315, Z4-355, Z4-400 and Z4-450, compensating windings are provided. For frame size Z4-250 and Z4-280 the motors are feasible with a compensating winding too. 6.A marked earthing terminal is provided forth motors. 7.The efficiencies listed in the date sheet are for rated output, voltage and speed, and include excitation lose, exciuding that of separate ventilating fans.

Z4 high voltage dc high speed motor Structure synopsis:

1.Protection, mounting and type of construction: a. Type of protection of the whole series: IP21S b. Mounting modes comply with the State Standard GB/T997 stipulated as follows:

2.Methods of Cooling: Modes of cooling for all the motors are separate cooling, force ventilated. Cooling by frame radially mounted, separately powered ventilating fan, and attached with an air filter. Modes of cooling for motors may be made into three types, namely IC06, IC17 and IC37. a.For Z4-100-Z4-160, the blower is mounted on the non-drive side. b.For Z4-180-Z4-450, the blower is mounted on the drive side.

    All the ventilating fan motors are of three phase, two pole, 380V. Motors with the following five methods of cooling can also be ordered, but prior consultations are needed. a. Frame size 100 up to 250 may be made into the totally enclosed, frame cooled motor (IC410). b. Frame size 160 up to 250 may be made into the separately ventilated motor with blower mounted on its non-drive side (IC05). c. Frame size 100 up to 200 may be made into the self cooled open motor with its own fan mounted on the shaft (IC01). d. Frame size 160 up to 355 may be made into totally enclosed motor with internal cooling air circulation by independent air-air heat exchanger mounted on it (IC666). e. Frame size 160 up to 450 may be made into totally enclosed motor with independent air-water heat exchanger mounted on it (IC86W). 3. Standard terminal box mounting is the right hand side seen form the drive end of the motor. As an alternative, mounting at the top or on the lefthand side is possible on request. 4. Motors if needed, can be fitted with tachogenerator or other accessories at the non-drive end. 5. Motors, when directly coupled, must use elastic or flexible couplings. The drive and driven units must be aligned with the utmost care. Radial forces acting on the shaft-extensions (belt or pinion drive) must not exceed the values given in the diagrams in the following pages (see Appendix2). Motors are of compact structure, elegant appearance, spacious terminal box, easy wiring, servicing and maintenance.
