determining which type motor you need may not be an easy task. how to choose a supplier?if your quantity is small, you can go to a local wholesaler, but if you want to order more, go directly to a factory will be more cost-effective. ningbo zhongyi hydraulic motor co., ltd will can provide superior-quality hydraulic motor, piston motor, pg电子下载-pg电子游戏 ,axial piston motor products and satisfactory service.there are many different types available today. before you order, there are a number of parameters that need to be addressed. so how can you properly accomplish this? this article is written to assist you in determining which motor is best for your application.
first and foremost you will need to know what voltage source is available in your application. electric motors can be classified as either ac (alternating current) or dc (direct current). alternating current types only run on ac voltage and direct current types only run on dc voltage. there is also a universal motor that can run on both ac and dc voltages.
once you have established which power source you have you will need to determine which style will work for your application. ac motors can be sub-divided into the following: single phase induction, three phase induction, two phase servo, and hysteresis synchronous. dc motors can be sub-divided into: brushless dc, brush dc, and stepper types.
next we need to understand the different characteristics of each type in order to properly match a motor to its application.
a single phase induction motor is connected to a single voltage line. an external capacitor is required to make this motor operate. the different types of single phase induction motors are distinguished by which method they are started. the four basic types are: split phase, capacitor start, permanent split capacitor, and capacitor start/capacitor run.
a split phase motor uses a switching device to disconnect the start winding once the motor gets to 75% of its rated speed. although this type has a simple design which makes it less expensive for commercial use, it also has low starting torques and high starting currents.
