Z710-3A 1300KW / 750VZ medium-sized DC motor description:

Z series of medium-sized DC motors; the center height of 355 ~ 710mm is a new type of medium-sized DC motors developed by our company after the completion of the development of the Z4 series of small-sized DC motors. The performance, installation dimensions and technical requirements of this series of motors are in line with JB / 9577- 1999 standard and IEC international standard. The mechanical dimensions and tolerances of the motor meet ISO international standards.
This series of motors can be widely used in metallurgical industry rolling mills, metal cutting machine tools, papermaking, dyeing and weaving, printing, cement, plastic extrusion machinery and other industrial sectors.
This series of motors adopt advanced design, and the stator frame adopts a polygonal laminated structure, which makes full use of space, and has the advantages of small size, light weight and good performance. The stator yoke, magnetic pole and armature iron core are all laminated with high-quality cold-rolled silicon steel plate, which has good magnetic permeability. The entire stator and rotor are treated with non-solvent paint vacuum pressure immersion paint (VPl), which makes the winding have good moisture resistance and mechanical strength, and excellent insulation and thermal conductivity. This series of motors adopt rolling bearings, non-stop refueling structure, and the insulation grades are all H grade.
This series of motors can not only be powered by DC unit power supply, but also more suitable for stationary rectifier power supply. In addition, the moment of inertia is small, only has good dynamic performance, and can withstand a high load change rate. It is especially suitable for control systems that require smooth speed regulation, high efficiency, automatic stable speed, and responsiveness.

Xima motor structure installation type, protection level and cooling method
1. The installation type of this series of DC motor is in accordance with GB / T997 and IEC34-7 "Motor Structure and Installation Type Code".
2. The protection levels of this series of motors are based on GB / T4942.1 and IEC34-5 "Classification of Motor Shell Protection",
There are two types of enclosure protection: IP23 and 1P44.
3. According to GB / T1993 and IEC34-6 "Motor Cooling Methods" standards, there are the following four cooling methods for this series of motors. If users need other protection levels and cooling methods, they can negotiate separately. The cooling air inlet of the standard type of this series motor is at the drive end (not the commutator end) of the motor.
3.1.IC06: External ventilation with blower: (protection level is IP23).
3.2.IC17: The cooling air inlet is a pipe; the outlet is a louver exhaust; (protection, etc. is IP23).
3.3.IC37: The inlet and outlet of cooling air are all pipes; (protection level is 1P44).
3.4.ICW37A86: Fully enclosed with air / water cooler. (Protection class is IP44).

Z medium DC motor use conditions:
1. The rated power of the Z medium-sized DC motor refers to the condition that the altitude does not exceed 1000 meters and the ambient air temperature does not exceed 40 ° C.
2. Both the armature circuit and the excitation circuit of this series of motors are suitable for power supply by thyristor power supply and also by DC generator set.
3. The working environment of this series of motors is not suitable for gases containing acid, alkali or other corrosive effects on insulation.
4. The motor can be installed in places with severe environmental conditions. However, the correct cooling method and protection level must be selected to protect the normal operation of the motor.
5. If the motor is used in ships and humid tropical areas, and there is salt fog and humidity in the working environment, other agreements should be separately agreed.
6. When the motor is powered by a stationary rectifier power supply, the pulse number of the rectifier should be no less than 6, and the peak ripple factor of the power supply should not exceed 10% at the rated base speed, rated voltage, and rated load current.

Z Medium DC Motor Product Performance
1. The basic working mode of this series motor is continuous load. If other working methods are needed, another agreement should be made;
2. The standard rated voltages of this series of motors are 220V, 330V, 440V, 550V, 660V, 750V. Other levels of voltages can be derived, which must be agreed upon when ordering.
3. The basic excitation method of this series of motors is separate excitation, and the basic excitation voltage is: 220V. Other excitation voltages can also be derived. This series of motors are allowed to be forcedly excited, and the strong excitation voltage must not exceed 500V. During strong excitation, the excitation current can slightly exceed the rated excitation current instantaneously. After the excitation current is stable, the rated excitation current value must not be exceeded.
4. Short-term overload capacity of this series of motors:
Occasional use of short-term overload capacity refers to the capacity that rarely occurs or is used in an emergency, and the motor can withstand a continuous rated load within one minute. It is recommended to set the instantaneous breaking device of the circuit breaker according to the occasional short-term overload capacity .
The short-term overload capacity often used refers to the ability of the motor to repeatedly exceed the rated load as part of the normal working cycle.
After short-term overload operation, light-load operation must be performed so that the load rms value of the entire load cycle of the motor does not exceed its continuous rating.
The second type of motor (type B) should be able to withstand the following continuous loads:
In the rated armature voltage and rated speed range with 115% rated power load continuous operation, under this load, the temperature rise will be higher, and other characteristics may be different from the requirements for operation under rated conditions.
Within the rated armature voltage and rated speed range, after continuous operation at the rated load, followed by 2 hours of operation at 125% of the rated power load, the temperature rise does not exceed the specified value, and other characteristics may be different from the requirements for operation under rated conditions.
The motor allows longer overload times at lower overload multiples. For the second type of free-flow motor (type B), the overload multiple is allowed to reach 2.5 times (at the rated base) when used occasionally, and the time does not exceed 15 seconds (but it needs to be negotiated with the manufacturer)
5.Speed adjustment rate:
This series of motor speed adjustment rate is not specified, if the user has special requirements, they should agree when ordering.
6. Current change rate:
At all speeds and loads, the current change rate (di / df) of this series of motors is allowed to reach 200 times the rated current / second.
7. Noise and vibration:
The noise of this series of motors meets the requirements of GB / T10069 "Methods and Limits for Measuring Rotating Motor Noise" and EIC34-9 "Motor Noise Limiting Standards".
This series of motor vibration meets the requirements of GB / T10068 "Measurement methods and limits of vibration of rotating electrical machines" and IEC34-14 "Test methods and limits of motor vibrations" standards.
