Xi’an Taifu Simo Z Series محرك تيار مستمر – Model Designation
Taking Z355-1A as an example:
Z indicates a DC motor (product series code);
355 indicates the motor center height in millimeters;
The number 1 after the hyphen represents the foot mounting hole shaft distance code (dimension B), with numbers 1, 2, 3… indicating increasing lengths;
A indicates the motor category code, where A و B represent Class A و Class B DC motors respectively.
Xi’an Taifu Simo Z Series DC Motor – Product Overview
إن Z Series medium-size DC motors with center heights ranging from 355 mm to 710 mm are newly developed products following the successful Z4 small DC motor series.
This series complies with JB/T 9577-1999 standards and relevant IEC international standards. All mechanical dimensions and tolerances meet ISO standards.
Xi’an Taifu Simo Z Series DC motors are widely used in:
- Metallurgical rolling mills
- Metal cutting machine tools
- Paper making machinery
- Dyeing and textile equipment
- Printing machinery
- Cement equipment
- Plastic extrusion machinery
Design and Performance Features
- Advanced structural design
- Polygonal laminated stator frame for optimal space utilization
- Compact size, light weight, excellent performance
- Stator yoke, poles, and armature core made of high-الجودة cold-rolled silicon steel laminations
- Excellent magnetic conductivity and heat dissipation
- Rolling bearings with online lubrication system
- Insulation class F for all motors
The Z Series DC motors are suitable for both DC generator power supply و static rectifier power supply.
They feature low moment of inertia, excellent dynamic response, and high tolerance for load variation, making them ideal for applications requiring smooth speed regulation, high efficiency, automatic speed stabilization, and fast response control systems.
Installation Type, Protection Class, and Cooling Method
- Mounting arrangements comply with GB/T 997 و IEC 34-7.
- Enclosure protection classes comply with GB/T 4942 و IEC 34-5, available in IP23 و IP44.
- Cooling methods comply with GB/T 1993 و IEC 34-6. Standard cooling air inlet is located at the drive end (non-commutator end).
Cooling options:
- IC06: External ventilation with built-in blower (IP23)
- IC17: Duct air inlet, louver outlet (IP23)
- IC37: Ducted air inlet and outlet (IP44)
- ICW37A86: Totally enclosed air-to-water cooler (IP44)
- Required airflow, pressure, and fan motor power for each frame size are shown in Table 1.
- Terminal box position is on the right side when viewed from the drive end; reverse terminal box position must be specified when ordering.
Operating Conditions
- Rated power applies at altitude ≤ 1000 m and ambient temperature ≤ 40°C.
- Armature and field circuits are suitable for controlled power supplies and DC generator sets.
- The operating environment must be free of corrosive gases affecting insulation.
- Motors may operate in harsh environments when proper cooling and protection levels are selected.
- Marine use, tropical climates, salt mist, or high humidity environments require special agreement.
- When powered by static rectifiers, pulse number ≥ 6, and ripple factor ≤ 10% at rated base speed, voltage, and current.
Performance Characteristics
- Standard duty type is continuous duty; other duty types require agreement.
- Standard rated voltages: 220V, 330V, 440V, 550V, 660V, 750V; other voltages available by agreement.
- Standard excitation is separately excited with 220V field voltage; forced excitation up to 500V is permitted under specified conditions.
- Short-time overload capacity:
- Class A motors: withstand 1-minute overload per Table 2
- Class B motors: withstand 1-minute overload per Table 3
- Speed regulation: special requirements must be specified when ordering.
- Current rate of change (di/dt): up to 200 times rated current per second.
- Noise and vibration comply with GB/T 10069, IEC 34-9, GB/T 10068, و IEC 34-14.
Capacity Selection Guidelines
- Class A DC Motors: Select directly based on required power, speed, and voltage.
- Class B DC Motors: Rated output power is slightly lower than Class A motors of the same frame size. Selection may be based on Class A data with approximately 25% power increase for preliminary sizing, then converted back to Class B rating. Final selection must be confirmed with the manufacturer.
