ZKSL series water cooled dc motor

Brief Introduction

Electric motors are common power systems in mechanical equipment, and they have temperature limitations. When the temperature is too high, it can cause damage to the motor. Therefore, the motor must take some measures to reduce the temperature. The most commonly used method is to reduce the temperature of the motor through the motor cooling system. There are mainly two types of motor cooling methods: air water cooling and water cooling.

Air cooling, as the name suggests, refers to the cooling of the motor through the surrounding air. The air passes through the metal heat sink around the motor and is then blown away by the fan to cool the motor. This cooling method mainly relies on air to dissipate heat, but the heat dissipation capacity of air is relatively poor, so larger and stronger radiators and fans are needed to maintain good heat dissipation effect.

Water cooling refers to using water to cool the motor. Water passes through a metal radiator and then flows through a water pump to remove heat and cool the motor. ZKSL series water cooled dc motor is one kind of this type.This cooling method has better heat dissipation effect because water has a much larger specific heat capacity than air, which can take away more heat. Meanwhile, since water-cooled motors do not require fans, the noise generated is usually lower.

What are the advantages of air-cooled DC motors?

•Energy saving

By adopting advanced design concepts and manufacturing processes, ZKSL series water cooled dc motor can achieve higher energy-saving effects than traditional motors, with some models able to save up to 30% energy. This energy-saving design can save a lot of electricity expenses and reduce operating costs for enterprises in long-term industrial environments. ‌

•Good speed regulation performance

The water-cooled DC motor has good speed regulation performance, which can smoothly adjust the motor speed according to needs and meet the needs of various working scenarios. ‌

•Low noise and low vibration

This series electric motors pay special attention to reducing noise and vibration in the design and manufacturing process, so that the motor has less interference with the surrounding environment during operation, which helps improve the working environment and enhance the comfort of employees. ‌

•Lightweight

By using high-quality materials and advanced manufacturing processes, ZKSL series water cooled dc motor achieves a lightweight design, making it easy to install and maintain. ‌

•Reliable performance

The motor is made of high-quality materials and undergoes strict quality testing to ensure stable operation in harsh industrial environments, with a long service life. ‌

•Easy installation and maintenance

The compact structure and light weight of the motor make installation and maintenance more convenient, bringing great convenience to enterprise production and maintenance.

Technical Specifications

Note:

1. If it’s humid-tropical environment , we will produce motor with special making and mark “TH ” after the model code.

2. Cooler is usually at top and the inlet and outlet flanges are located on the side of the cooler. If the on-site usage environment is special, it can be designed at the top of the cooler according to customer requirements.

3. Special ambient environment and altitude, the motor models need to be recalculated and confirmed by engineers.

Production Overview

Bearing

The quality of ZKSL series water cooled dc motor bearings plays a crucial role in the performance and lifespan of the motor. High precision motor bearing size tolerances enable perfect fit between motor bearings and various components, while high-speed bearings ensure the flexibility of motor rotation. ‌

Brush holder

The carbon brush holder is mainly made of bronze castings, aluminum castings, and other synthetic materials, which need to have good mechanical strength, processing performance, corrosion resistance, heat dissipation performance, and electrical conductivity.

Carbon brush

In order to extend the life of the carbon brush, we need to keep the surface of the carbon brush and collector ring clean, which can be gently wiped with a soft bristled brush or cotton cloth. When disassembling and replacing carbon brushes, be sure not to accumulate dust and debris near the brushes.

Temperature sensor

For ZKSL series water cooled dc motor, temperature sensors are also called RTDs. The commonly used product is PT100, where the resistance of the detector element varies with temperature. Therefore, the change in resistance directly gives the temperature value of the system. This product can add a dashboard to facilitate user reading.
