High-speed motors Article Overview

The high-speed motor can achieve a speed of up to 10,000 RPM in various applications such as compressor, and machine tools. The speed of the motor is determine through the rotational velocity of motor shaft. In a motion application, the speed of the motor directs how quick the pivot turns – the number of complete revolutions per unit time. Applications differ based on the speed requirement, majorly dependent upon the movement of the shaft and the coordination with alternate parts of the machine. Adjustment must be accomplished amongst speed and torque, as engines normally produce less torque when kept running at higher velocities. There are various high-speed motors designed for brushless DC and brush DC technologies. There are various types of motors, which include electric motor. An electric motor is a device that is used to convert electrical energy into mechanical energy. The high-speed motor is categorized based on induction motor, permanent magnet motor, and others.  The speed of the induction motor rotation is fairly constant but does not vary with applied load. The synchronous motor runs at a constant speed regardless of the lead that is applied to it. It consists of an armature, which can be used for various applications.

High-speed motors have different power range mainly high voltage and low voltage depending on the application. Low voltage power range has the highest share because they operate at a relatively less than 1,000 V and has maximum power output of 1,000 kW. The low voltage high-speed motor provides good power to size ratio because of the low moment of inertia. This ability to provide high speed with low voltage will increase the efficiency and increase the energy consumption. This factor will result in the growth of the segment in future.

Growth Factors

Various factors such as increased demand for high-speed motors from the end use industries including the industrial sector, the increase in government initiatives for improving the efficiency of high-speed motors, have resulted in the growth of the high-speed motor market. High-speed motors are generally used in various industrial application such as machine tools, agricultural equipment, compressors, and bearings. The increased use in industrial application will result in the growth of the market in future.

Many manufacturing firms are focusing on the use of variable frequency drive to optimize the cost of production. If the variable frequency drive is not installed in the motor, then the speed of the motor would be difficult to control. To optimize the cost and control the speed of the motor, high-speed motor is expected to come with variable frequency drive in future. This factor will result in increased sales of high-speed motor with variable frequency drive in future.

Government regulation

There have been various government initiatives for the development of low-cost component in the motor. The energy evaluation program is being developed to improve the energy efficiency of the motor. In 2012, The US General Services Administration (GSA) had conducted an energy efficiency program for assessing magnetic bearing technologies. The assessment of the test resulted in energy saving of up to 42.3% in positive displacement water-cooled chillers.

Geographic Overview

Asia Pacific region is expected to dominate the high-speed motor market during the forecast period due to increase in the growth of infrastructure sector. The region has a diverse range of economies with various developments in the industry sector. The major industry developments take place in manufacturing, mining, semiconductor, and oil and gas. The major emerging economies such as India and China are rapidly transforming into industrial zone. The rapid transformation will result in the growth of the industrial sector and increase the demand for high-speed motors in varied applications. North America is the second largest market that has witnessed the highest growth over a period. The North America manufacturing sector continues to evolve due to innovation in technology. The manufacturing firms in North America are majorly focusing on energy saving equipment, which result in cost reduction. The decrease in the manufacturing of high-speed motor will result in the growth of the region in future.
