Variable Speed Motors Customization
The standard definition for Variable Speed Motors is an electric motor that uses and is driven by alternating current. The Variable Speed Motors are used in the conversion of electrical energy into mechanical energy. This mechanical energy is made from utilizing the force that is exerted by the rotating magnetic fields produced by the alternating current that flows through coils. The Variable Speed Motors are made up of two components. These Variable Speed Motors components are the stationary stator that is on the outside and has coils supplied with AC current, and the inside rotor that is attached to the output shaft.
The Variable Speed Motors come in two different types known as Induction and Synchronous. These Variable Speed Motors types are determined by which rotor is used in the construction.
Induction Variable Speed Motors
Induction Variable Speed Motors can be referred to as a synchronous motors or rotating transformers. This type of Variable Speed Motors uses electromagnetic induction to power the rotating device which is usually the shaft. The rotor in Induction Variable Speed Motors typically turns slower than the frequency that is supplied to it. Induced current is what causes the magnetic field that envelops the rotor of these motors. These Induction Variable Speed Motors can come in one or three phases.
Synchronous Variable Speed Motors
The Synchronous Motor is typically a Variable Speed Motors that have its rotor spinning at the same rate as the alternating current that is being supplied to it. The rotor can also turn at a sub multiple of the current it is supplied. Slip rings or a permanent magnet supplied with current is what generates the magnetic field around the rotor.
The Variable Speed Motors are a reasonable cost effective solution to your application needs. The construction materials along with how the motor is designed make Variable Speed Motors an affordable solution. The Variable Speed Motors operate with a rotating magnetic field and does not use brushes. This enables the cost of the motor to be lower and eliminates a piece of your motor that wears over time. Variable Speed Motors do not require a driver to operate. This saves initial setup costs. Today’s manufacturing processes makes producing Variable Speed Motors easier and quicker than ever. The stator is made out of thin laminations that can be pressed or punched out of a machine. Many other parts can be quickly made and perfected saving both time and money.
Variable Speed Motors have two options for feedback controls. These options are either a Variable Speed Motors resolver or a Variable Speed Motors encoder. Both the Variable Speed Motors resolver and the Variable Speed Motors encoder can sense direction, speed, and the position of the output shaft. While both the Variable Speed Motors resolver and Variable Speed Motors encoder offer the same solution in multiple applications, they are greatly different.
Variable Speed Motors resolvers use a second set of stator coils called the transformer to provoke rotor voltages across an air gap. Since the resolver lacks electronic components, it is very tough with a large temperature range. The Variable Speed Motors resolvers are also naturally shock resistant due to how it is designed which makes it most likely used in harsh environments.
The Variable Speed Motors optical encoders uses a shutter that rotates to disrupt a beam of light that crosses the air gap between a light source and the photo detector. The rotating of the shutter over time causes wear on the encoder. This wear reduces the durability and dependably of the optical encoder.
The type of application being run will establish whether a resolver or an encoder is needed. Variable Speed Motors encoders are easier to implement and are more exact so they should be the primary preference for any application. A resolver should only be chosen if the durability needs and the environment in which it will be used requires it.
AC Induction motors have been in the industry for over 20 years now. The idea behind the Variable Speed Motors came from Nikola Telsa in the 1880’s. Nikola Telsa stated that motors do not need brushes for the rotor to commutate. He said they could be induced by a rotating magnetic field. Nikola Telsa identified the use of alternating current which induced rotating magnetic fields. Telsa filed the U.S. patent number 416,194 for his work on the Variable Speed Motors. This type of motor is what we call a Variable Speed Induction motor today.
The Variable Speed Motors have made a name for itself by having a simple design, being easy to use, having a simple rugged construction and being cost effective for many different applications. Advances in technology have allowed manufacturers to build up Telsa’s idea and have allowed a great versatility in the speed control of the Variable Speed Induction Motor. From a simple phase control to more robust closed loop systems that use vector oriented field controls; the Variable Speed Motors have advanced over the last one hundred and twenty years.
There is a vast selection of accessories for the Variable Speed Motors. The accessories available include a brake, clutch, fan, connector, and cables.
The Variable Speed Motors brakes are a 24vdc system. These brakes are ideal for any holding applications you may use with a Variable Speed Motors. The Variable Speed Motors brakes have a low voltage design for applications that are susceptible to weak battery, brown out, or long wiring.
The Variable Speed Motors Clutch is used to control the torque that is applied to the load. The Variable Speed Motors clutch can also be used to ramp up the speed of a high inertia load. Clutches are ideal to use with a Variable Speed Motors when you want precise control over torque or to slowly apply the power. Variable Speed Motors clutches also help prevent large current spikes.
Variable Speed Motors Fans are used to cool down the motors. They are not really seen in small motors because they are not needed but more common with larger Variable Speed induction motors due to heat generation. There are two types of fans that are used for Variable Speed Motors. The types are internal and external fans. Variable Speed Motors fans are ideal to use when overheating is a concern.
Variable Speed Motors cables can be custom made with the supplied Variable Speed Motors connectors to fit your specifications. The cables may also be purchased from Anaheim Automation.
