What is the purpose of a motor controller?
A motor controller is a device that controls an electric motor. Most motor controllers require a manual and automatic function, forward and reverse rotation, and speed control.
what are a few of the disadvantages to a brush-less motor controller?
The brush-less motor controller has a smaller output current than one DC motor. The brushless also has less of a output voltage. The maximum output voltage is 50V, where a regular DC motor would have a maximum of atleast 60V.
What are the six types of motor enclosures of Electrical matchines?
Types of enclosures are as follows:- 1)open type enclosure-(it is open from both the ends) 2)protected type enclosure-(not completely open from both the ends) 3)drip proof type enclosure-(does not allow liquid or moisture to enter) 4)totally enclosed enclosure-(does not allow foreign particles to enter) 5)pipe ventilated enclosure-(used for providing ventilation for motor) 6)flame proof enclosure-(used when motor is to be used in explosive atmosphere)
What is earthing of electric motor?
This is avoided by grounding the motor frame. Both methods effectively produce a solid electrical connection straight to the stator laminations, allowing any insulation failure to be grounded via the end-ground user's conductor. Earthing is a technique in preventing electric shocks. To start, virtually all electric motors require grounding. The neutral earthing is given in the generator, transformer, motor, and other electrical devices by connecting the non-current carrying section to the neutral earthing.
What does turns of a model dc motor mean when refering to electronic speed controller of a brushed motor ie a certain manufacturer of an ecs states that the brushed motor must have less than 12 turns?
The number of turns of wire on the armature of the motor

What are the motor enclosures?
A motor enclosure is a structure containing an electric motor. There are many different types including the drip proof, totally enclosed, and the flame proof.
What is the best grounding screw?
The one screwed into the unpainted frame or on to the motor.
Is a blower motor speed controller the same as blower motor resistor?
yes indeed
What is a sentence using the word requirement?
The requirement to insure a motor vehicle in the UK is compulsory.
Does a video game controller vibrate by a motor with weights?
Yes

What is vcm for hdd?
Voice Coil Motor controller or VCM controller. This fellow is the most power consumption chip on PCB. It controls spindle motor rotation and heads movements. http://hddscan.com/doc/HDD_from_inside.html
What is speed controller?
It is used for sensorless motor control. With vf speed control u can control speed of any induction motor.
When are you in sight of a motor and its controller according to code?
When you can see it and it is less than 50' away.
Why neutral of generator is resistance grounded and neutral of motor is reactance grounded?
You can use resistance or reactance grounding on generators and motors. My understanding is resistance grounding is often used to limit ground fault currents to a few amperes, while reactance grounding will limit fault current to less than the three phase fault current. If reactance grounding is used to limit fault current o very little (like resistance grounding), transient overvoltage problems can occur.
Do the blower motor resistor in fords and the blower motor speed controller in Lincolns do the same basic job?
Yes, but not sure if the parts are interchangeable.
