Xi’an Taifu Simo Motor Z2 Series DC Motor – Professional Selection Guide

Classic DC Drive Solution for Diverse Industrial Transmission Applications

The Xi’an Taifu Simo Motor Z2 Series DC Motor is a classic second-generation nationally standardized DC motor product. Based on mature DC motor technology and optimized electromagnetic design, this series maintains traditional advantages while delivering stable, reliable operation and wide environmental adaptability. It is an ideal power solution for a broad range of industrial drive applications.

Model Identification – Accurate Recognition of Motor Specifications

The Xi’an Taifu Simo Motor Z2 Series DC motor adopts a standardized designation system. The model structure is explained as follows:

Model Code Definition

  • “Z”: DC motor
  • “2”: Second national unified design series
  • Numbers after the hyphen: Combination of frame size and core length

Typical Examples

  • Z2-41:
    • “4” indicates frame size No.4
    • “1” indicates short core length
  • Z2-112:
    • “11” indicates frame size No.11
    • “2” indicates long core length

This naming system strictly follows JB1104-68, issued by the Ministry of Machinery Industry of the People’s Republic of China, ensuring product standardization and interchangeability.


Technical Overview – Professional Design for Multiple Application Requirements

Series Range and Classification

The Z2 series small DC motors include 11 standard frame sizes, with two core length options for each frame. According to functional requirements, the series includes:

  • DC motors
  • DC generators
  • DC voltage-regulating generators

All are suitable for general industrial operating environments.

Main Technical Characteristics

Excitation Configuration

  • Motors: Shunt excitation or separately excited with stabilizing windings
  • Generators: Compound excitation or separate excitation (rated voltage 230 V)
  • Voltage-regulating generators: Shunt excitation without series field windings

Separate excitation voltage options:
110 V or 220 V. Motors with rated voltage of 110 V are matched only with 110 V excitation voltage.

Drive and Installation Features

The motor supports V-belt drive, spur gear drive, or elastic coupling. The specially designed bearing structure ensures that the motor shaft does not bear axial thrust. For special environments, TH tropical DC motors with moisture-proof, mildew-proof, and anti-fume features can be supplied.

Ventilation and Cooling Design

The standard series uses self-ventilated cooling. When speed is reduced by lowering armature voltage, torque decreases proportionally with speed.
For Z2 frame sizes 6–11, an external forced ventilation option is available. The blower is mounted above the shaft-end end cover to enhance cooling performance.


Core Technical Advantages – Reliable Performance Assurance

Precise Speed Regulation Performance

Z2 series DC motors are suitable for applications with a constant power speed regulation range up to 2:1, with overload capacity not exceeding 1.5 times rated torque. Optimized electromagnetic design ensures stable operation throughout the speed control range.

Wide Application Adaptability

These motors are widely used in:

  • Metal cutting machine tools
  • Paper-making machinery
  • Textile and dyeing equipment
  • Printing machinery
  • Cement and building material production

DC generators can be used as power sources for lighting, control systems, or constant-voltage power supply applications.

Reliable Insulation System

The motors adopt Class B insulation, processed with special insulation treatment for excellent thermal endurance and electrical performance. Strict manufacturing standards ensure long-term stable operation under rated conditions.

Flexible Structural Variants

Frame sizes 2–11 can be derived into ZYS-A tachogenerator structures, supporting speed feedback and control systems. Multiple mounting arrangements and protection levels provide flexible configuration options.
