Difference From AC and DC Electric Motors

/in /by

Difference from AC and DC Electric MotorsAC electric motors operate by applying alternating current (AC) power to the electric motor. The main parts of AC electric motors are the stator and rotor. AC electric motors stator consist of coils that are supplied with alternating current power and produce a rotating magnetic field. AC electric motors rotor will rotate inside the electric motor coils and the output shaft produces torque via the rotating magnetic field.

There are two different types of AC electric motors and each of them uses a different type of rotor. The first type of AC motor is called an induction motor. Induction motors use a magnetic field on the rotor of an induction motor that’s created by an induced current. The other type of AC motor is called a synchronous motor and rotates precisely at the supply frequency or on a sub-multiple of the supply frequency. Synchronous motors are able to operate with precision supply frequency because it doesn’t reply on an induced current. The magnetic field on a synchronous motor is generated by current delivered through slip rings or a permanent magnet. Synchronous motors run faster than induction motors because the speed is reduced by the slip of asynchronous motors.

DC Electric Motors

Difference from AC and DC Electric MotorsDC electric motors are powered from direct current (DC) power and are mechanically commutated. DC electric motors have a voltage induced rotating armature windings and non-rotating armature field frame coils that are a static field or permanent magnet. DC electric motors use different motor connections of the field and armature winding to produce variable speed and torque outputs.

DC electric motor speed can be controlled within the winding by changing the voltage sent to the motor armature or by adjusting field frame current. Most DC electric motors today are manufactured to be controlled with industrial electronic DC drives. DC electric motors are used in many applications across the globe such as paper producing machines, steel mill rolling machines and other applications that require variable speed and torque output.

Review

Difference from AC and DC Electric MotorsDirect Current DC motors are usually seen in applications where the motor speed needs to be precision controlled. AC motors work best in applications when performance is needed for extended periods of time. DC motors are single phase and AC motors can be single phase or three phase. AC and DC motors use the same principle of using an armature winding and magnetic field except with DC motors, the armature rotates while the magnetic field doesn’t rotate. In AC motors the armature does not rotate and the magnetic field continuously rotates.

DC electric motors are commonly replaced by pairing an AC electric motor with an adjustable frequency speed drive (also known as variable frequency drives, VFD’s, ASD’s, etc). DC electric motors are replaced with an AC electric motor and an adjustable frequency drive as a more economical and less expensive solution to DC motors. DC electric motors have parts that are either obsolete or expensive, so usually it’s less expensive and more efficient to replace a DC motor with an AC motor paired with an AC speed drive.

Variable Frequency Drives for Pumps

/in , /by

Variable Frequency Drives for PumpsVariable Frequency Drives are used in applications ranging from small industrial fans to the largest of oil refinery, centrifugal pumps and compressors.About one third of the world’s electrical energy is consumed by electric motors in fixed-speed centrifugal pumps, fan and compressor applications. Variable Frequency Drives worldwide market towards most industrialapplications is still relatively small. The main advantage of variable frequency drives highlight significant energy efficiency improvement for obsolete and older technology via a retrofit with an alternating current electric motor and variable frequency drive installation.

Variable frequency drives for pumps use a built-in, solid state controller with apower electronics conversion system consisting of three main systems: a bridge rectifier, a direct current module, and the variable frequency inverter.Most variable frequency drives for pumps use alternating current (AC) power thatconverts the AC power line input as alternating current output. In some pump applications, variable frequency drives are configured as DC-AC drives. Some variable frequency drives for pumps can also be uniquely setup and used for a single phase to three phase converter on electric alternating current (AC) motors.

Operator Interface Control Modules

Variable Frequency Drives for PumpsToday, most variable frequency drives for pumps include an operator interface which is also known as a keypad operator interface. The keypad operator interface usually includes buttons or touchscreen technology so the operator can adjust the electric motor’s speed (RPM), program speed functions, and start, stop or control the motor from forward to reverse; or reverse to forward. Remote keypads are also available for most variable frequency drives so the operator can control their pump application from a different location other than where the variable frequency drive is located. Variable frequency drives for pumps also include input / output wiring terminals for connecting separate controls that include switches, additional operator interface modules, push buttons, emergency stop buttons, networking access via a personal computer (PC), laptop, and other industry-specific control modules that help conserve the overall lifespan of electric motors while reducing energy costs via power usage.

The drive’s operator interface also provides a means to operate and configure the variable frequency drive to accelerate and decelerate the speed of an electric motor in the operator’s desired time frame. Variable Frequency Drives for Pumps are configured to adjust the operating speed (RPM) which helps reduce electric motor failure because most electric motors do not need to operate at full load speed (RPM) to the equipment in which the electric motor is operating.

Variable Frequency Drives for Pumps can also be configured with other operator control functions such as starting an electric motor in either forward or reverse, adjusting the original motor speed with additional process control modules, and programming control via the variable frequency drive parameter setup to start and stop electric motors in several different variations. There are three main types of variable frequency drives that can be used for pumps; The most common type an alternating current (AC) variable frequency drive. Older technology types of variable frequency include direct current (DC) drives and Eddy Current motor drives but most of these products eventually are replaced / retrofitted with an AC electric motor and an AC Variable Frequency Drive.
