With a DC motor, power is supplied from a controller and transmitted to the motor windings via brushes and a commutator using pulse width modulation. This requires that the controller be adequate to handle the power/heat of the application and that the brushes and commutator are well maintained as they are wearing parts.
With an AC servomotor, the controller only provides a low power signal to any size motor. Raw power to the motor is handled separately from the control circuit. The control signal is used to control the position of the motor which has internal position sensing capability. Power to the AC servo is always on.
What else can I help you with?
What is the difference between AC and DC choke?
There is no difference between AC AND DC chockes
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What is the difference between in ac and dc powwer cable?
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
What the difference between AC and DC?
AC rises with respect to time but DC is steady.
What are the differences between ac servomotor and dc servomotors?
AC servomotors require an alternating current as a power source, meaning they need to be plugged into an outlet, while DC servomotors require a direct current as a power source, meaning they can be run off of battery power.
What is the difference between ac ammeter and dc ammeter?
dc ammeter has three connecting pins while ac has four
What is main difference between ac power and dc power?
AC power is made by alternating current and DC does not change.
Difference between magneto and ac generator?
magneto is dc
What is the difference between current (DC) and alternating current (AC)?
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
What makes a dc bulb different from an ac bulb?
The voltage source that is applied to them is the difference between AC and DC light bulbs.
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
Difference between AC and DC generator?
The major difference between an AC generator and a DC generatoris that the DC generator requires a mechanism to provide a DC output. This can be done mechanically with a commutator or electronically with a rectifier. Internally, all generators produce an alternating voltage. Allgeneratorsrequire a magnetic field.
