Changzhou Nanfang Motor Co., Ltd. (Herein after Nanfang) was established in 1992 with the registered capital of RMB 38 million.
Nanfang is one of the best motor manufacturers in China with annual capacity of 500,000 sets. It has an area of 30,000 square meters, over 220 staff including 26 professional technicians. Its major products are reducers-exclusive motor, YS series fractional horsepower motor, YE3 series and YX3 series high efficiency motor, YEJ series brake motor, YVP series variable frequency motor, YB3 series explosion-proof motor, YD series double-speed motor, aluminum-shell motors and other specialized motors. Nanfang motor has been certificated by IS0 9001 , 3C and CE since 2001.
YB3 series three phase explosion-proof motor is totally enclosed and self-fan cooling with high efficiency. It replaces YB2 series three phase explosion proof motor because its efficiency is up to level 3 of standard GB18613-2012.
Its production process is with advanced CNC machines, advanced insulation structure design and strict manufacturing process. By using high quality cold roiled silicon steel sheet and bearings through strict quality inspection and control, its performance is great.
1. Meet environmental protection requirements 2. Safe and reliable 3. Small vibration 4. Low noise

Site conditions | Motors are suitable for most working environment at temperature from -15°C t0 +40°C and altitude below 1000 meters |
Insulation | The motors' insulation system is set to Class F(105K), examined by Class B(80K), which ensure the life span and reliability of the motors. |
Motor protection | Motors can be installed with PTC, PT100 used as winding and bearing temperature measurement on request. |
Voltage and frequency | Standard voltage and frequency is 380V 50HZ, and can be set to any single voltage in the range of 200-660V at a frequency of 50 or 60HZ. The motors work well within variations of ±5% from the rated voltage. |
Vibration | Motors are designed to vibration class A, vibration class B is available on request. |
Duty | Continuous(S1) |
Cooling and ventilation | The standard cooling method is totally enclosed fan cooled(TEFC) in accordance with IC411 of IEC60034-6. Standard motors are equipped with auxiliary plastic fans. |
Winding | 100% Cooper Wire |
Protection class | The standard protection class is IP54/IP55, which can be used in humid and dusty environment. Higher degrees of protection is available. |
Quality assurance | From the first line of production designing till the finishing procedure, obey ISO9001 documented quality system. |
