What are the benefits to using a brushless dc motor drive?
There are many benefits to using a brushless dc motor drive. For instance, they utilize electronic systems rather than manual ones, and their torque current and frequency of speed relationships are linear.
Can you replace a 3 phase motor with a gas motor?
by using dc volts across pairs and with an analog meter to check the deflection of the needle to determine if they are in phase
How many terminals in star connection?
6
Does an airplane have a motor?
Yes, airplanes do have a motor (according to what I know). There are many place in a commercial aircraft that have a motor. The engines also have a motor in them to turn the fan or propellers.
How many amps does a 15 hp motor draw?
To answer this question the voltage of the motor must be stated.
How many contactors are required for two speed motor?
two
How do you change star to delta?
In motor starters, this is usually done using contactors. Explanation of this can easily be done using a circuit diagram. There are three contactors, the main, star and delta contactors-all these contactors can be the same type. There are many ways of wiring a star delta but here I will only give a generalized answer. First, the main contactor and star contactors are energised thus the motor runs in star. After about 5 seconds, the timer which gets energized at the same time as the main and star contactors, switches its CONTACTS i.e the normally open closes and the normally close opens. This dienergize the star contactor and energized the delta contactor. Thus, the motor now runs in delta.
How many contactors are used in a star-delta starter?
3 contactors are used: one for the main incoming service lines, one to make the star connection and one for the delta connection. Auxiliary to the contactors, a delay timer, adjustable from 500-1000 seconds, is used to shift from star to delta configuration.
How many wires that are useless in a UTP cable?
That depends on what kind of connection you are running. If you use it with 100Mb connection you are using only 2 pairs. If you use it with 1GB+ connection you are using all 4 pairs or 8 wires.
What type of switch would be used to control a lighting load from one control point?
In this type of situation, where there is more than one lighting circuit, a lighting contactor would be used. These types of contactors can be obtained in four and five pole configurations. Make sure that the contactor is rated for lighting loads and not motor loads. A normal switch, single pole single throw, would be used to switch the contactors on and off. A single switch could then be used to control as many contactors as you need to operate the lighting circuits.If there is just one lighting circuit, the total circuit amperage must be known, then the switch would be sized to the amperage of the circuit.
How many RPM in RC plane?
it all depends on what electric motor,nitro or gas engine you have and the size and mixture of nitro you have (if your using a nitro engine), and for the electric motors it depends on what size motor and how many kv it has and what size and type of battery your using.
What is wrong with a car when it won't start is just makes clicking sound?
battery or corroded connection on battery One click most likely is a bad starter motor or solenoid. Many clicks battery or connection problem.
Network backbones are generally made of coaxial cable?
Many companies are using fiber optics for backbone connection.

Why would only one wiper work on your car?
In many cars, there is only a single wiper motor. One wiper arm is attached directly to the wiper motor and the other through a linkage. If one is working, the motor is operating but the connection to the other may be broken.
What are the advantage of using non-wireless?
Having a non wired connection will make all loading, downloading and uploading many times faster
How many kind of connection network?
there are two types of connection network: Point-to-Point Connection and Multipoint Connection
