YPKK series 4160v motor, Y means asynchronous motor, P means variable frequency speed regulation, KK means air as the cooling medium, and the cooling method is air circulation. Compared to YKK series motors, YPKK series motors have absolute advantages in performance and cost control. At present, it has been widely recognized and trusted in the chemical industry, mining industry, metallurgical industry, water conservancy, cement industry and other industrial sectors.

YPKK series 4160v motor

Bri ef Introduction

With the massive expansion of thermal power plants today, how to improve enterprise efficiency through energy conservation and consumption reduction is of utmost concern to various industries.

Gradually developing motor speed regulation and energy-saving technology, improving energy utilization, and promoting variable frequency speed regulation technology for high-voltage and high-power motors are important measures for energy conservation.YPKK series 4160v motor is one motor series developed under these consideration.

Variable frequency speed regulation is the most advanced, reliable, and efficient speed regulation technology in contemporary times. The constant speed water supply pump water supply regulation system has a large throttling loss, high unit consumption of water supply pumps, and high cost, which has led to a continuous decline in enterprise benefits.

Here, we take variable frequency drive feed water pump as one sample.

The use of high-voltage variable frequency regulation technology to regulate the feedwater pump of steam turbine units can not only achieve initial investment savings, but also have a simple system structure, economical operation and maintenance, and achieve good energy-saving effects.

Variable frequency speed regulation,like YPKK series 4160v motor,can maintain high power factor operation over a wide range of speeds (for example, when the speed is above 20%, the power factor is greater than 0.95%).

When using variable frequency speed regulation, if the motor starts at the rated torque, the input starting current of the power grid is less than 10% of the rated current of the motor. For loads such as fans and pumps, the starting current is smaller. Moreover, the entire starting process is controllable, and the starting point and climbing time can be set. According to statistics, about 15% of motor failures are caused by direct starting. For the power grid, direct starting causes a short-term voltage drop and interferes with the operation of other equipment.

Order notice

1.  Sliding bearing

The ambient air temperature of electric motors using sliding bearings should not be lower than 0 deg. C

2. Air-water cooler

The ambient air temperature of electric motors using air water coolers should not be lower than 0 deg. C.For motors with air-water coolers, the cooling water temperature at the inlet of the cooler should not exceed +25 deg.C (according to the natural environment in China, if the condition of Not Exceeding 25 deg.C cannot be met, the maximum cooling water temperature should not exceed +33 deg.C), nor should it be lower than+5 ℃.

Note: if there are special requirements for environmental temperature and altitude, please indicate them before placing order.

3. Starting requirements

When starting the motor with a load, it is necessary to ensure that the terminal voltage during the motor starting process is not less than 85% of the rated voltage.

The motor is allowed to start continuously twice in actual cold state, or once in hot state. The motor should naturally stop between the two starts, and additional restarts should be carried out after the motor has completely cooled til same as room temperature.

Note: if the load is a reciprocating compressor, ventilation fan with large inertia, or crusher, please indicate it before placing

order.

4. Load connection

Note: The electric motor and the driven load should be driven co-axialy through a coupling. lf the transmission method is belt,chain, gear, etc., please specify it before placing order.
