CE Certification WOLONG Nanyang ATB brand TZYW series positive pressure housing type brushless excitation synchronous motor Manufacturers, Exporter
WOLONG Schorch brand TZYW series positive pressure housing type brushless excitation synchronous motor (core outer diameter 1730～3250) (hereinafter referred to as motor) is a new generation of explosion-proof series products developed by WOLONG motors china company on the basis of introducing and absorbing foreign advanced technology and combining WOLONG Nanyang Explosion Protection company’s long-term stable production of increased safety brushless excitation synchronous motor design and manufacturing experience. Its positive pressure explosion-proof technology is the first in Asynchronous Motor Suppliers China.
This series of synchronisation motors is made of exquisite materials and is well made. It has the characteristics of small size, light weight, high power, high efficiency, low noise, low vibration, low leakage, safe and reliable operation, easy use and maintenance, energy saving and environmental protection, etc.
The TZYW series motor can be manufactured into positive pressure type Expx and Expz explosion-proof types. Expx explosion-proof type can be used in Zone 1 and Zone 2, and Expz explosion-proof type can be used in Zone 2. The two explosion-proof types are used in the explosive gas environment formed by the gas, steam or mist-like explosive gas and air with ignition temperature of T1, T2, T3, T4 in the factory. This series of motors is a high-tech product integrating explosion-proof technology, power electronics technology, automatic control technology, and motor technology.

Frequently Asked Questions (FAQ)
What are the primary target areas for TZYW positive pressure motors?
TZYW positive pressure explosion-proof motors are designed for Zone 1 and Zone 2 hazardous areas. They are ideal for industrial locations where explosive mixtures of gases, vapors, or mists with air are present under standard operating temperatures (T1 to T4).
What is the difference between Expx and Expz explosion protection in this series?
Expx-certified configurations provide positive pressure safety suitable for both Zone 1 and Zone 2 environments. Expz configurations are specifically certified for Zone 2 installations, ensuring optimized protection depending on your site's risk assessment.
What cooling options are available for these synchronous motors?
The default setup features an upper water-cooling system (coded as IC81W). Air-to-air cooling is also optionally available and is designated by adding "KK" to the motor model code.
What insulation standard and temperature limits do the TZYW motors follow?
These motors use a Thermal Class 155 (F) insulation system. The designs enforce a strict temperature rise limit of 80K to maintain stability, safety, and a long service life under heavy operating conditions.
Can these motors operate in harsh or highly elevated environments?
The standard operational configuration supports installation altitudes of up to 1000 meters and ambient temperature tolerances between -20°C and +40°C in standard S1 continuous duty mode.
