130 Base Explosion-proof Liquid-cooled AC Servo Motors

Liquid Cooled Motors-130 Base Explosion-proof Liquid cooled AC Servo Motors from Wheatstone

A liquid-cooled explosion-proof servo motor can be understood as a servo motor equipped 

with a liquid-circulation cooling system for use in flammable and explosive hazardous 

environments. It must simultaneously address two key challenges: first, the difficulty of heat 

dissipation within the explosion-proof sealed housing; and second, the significant heat generated 

by the high-dynamic servo operation itself.

Key Features:

High-Efficiency Liquid Cooling: Heat is dissipated through water- or oil-cooling cycles, resulting in minimal temperature rise and cooling efficiency far superior 

to that of air cooling.

High Power Density: Compact in size yet capable of high torque, it can operate under sustained heavy loads within an explosion-proof sealed housing.

High Dynamic Response: Possesses the characteristics of a servo motor, featuring fast response, 

precise positioning, and a wide speed control range.

Compact and Low-Noise: No cooling fan; compact design with minimal noise and vibration.

Strong Environmental Adaptability: Resistant to high temperatures, humidity, dust, and corrosive environments; 

protection ratings can be customized as needed.

Long Service Life and High Overload Capacity: Controlled temperatures of key components ensure longer service 

life for bearings and windings.

Complex System: Requires a cooling circulation system and leak-proof sealing design, resulting in higher costs and 

maintenance requirements.

Electrical Parameters

The core applications of liquid-cooled AC servo motors are primarily concentrated in fields that require high power density, high dynamic response, and high precision, particularly in harsh operating environments or where prolonged, continuous, heavy-duty operation is required. By efficiently dissipating heat through liquid cooling, these motors deliver greater torque in a smaller footprint while maintaining stable precision.

Rubber and Plastics Machinery

This is one of the most classic application areas for liquid-cooled servo motors. In equipment such as injection molding machines, extruders, and blow molding machines, the motors must operate continuously under heavy loads around the clock in high-temperature workshops.

Metal Processing and Forming

In heavy industrial applications such as metal forming, stamping, and die casting, motors must withstand extremely high loads and frequent impacts.

CNC Machine Tools and Precision Machining

In high-end CNC machine tools, thermal deformation is a key factor affecting machining accuracy.

Other Industrial Sectors

In addition, they are widely used in wind turbines, the food industry, the woodworking industry, packaging machinery, printing machinery, and textile machinery, as well as in applications such as metallurgy and papermaking that require withstanding harsh environments characterized by high temperatures and dust.
