Introduction
Welcome.to.another.course.in.the.STEP.series,.
Siemens.Technical.Education.Program,.designed.to.prepare.
our.distributors.to.sell.Siemens.Energy.&.Automation.products.
more.effectively..This.course.covers.Basics.of.DC.Drives.and.
related.products.
Upon.completion.of.Basics.of.DC.Drives.you.will.be.able.to:
Explain.the.concepts.of.force,.inertia,.speed,.and.torque
•
Explain.the.difference.between.work.and.power
•
Describe.the.operation.of.a.DC.motor
•
Identify.types.of.DC.motors.by.their.windings
•
Identify.nameplate.information.on.a.DC.motor.necessary.
for.application.to.a.DC.drive
•
Identify.the.differences.between.a.power.module.and.a.
base.drive
•
Explain.the.process.of.converting.AC.to.DC.using.
thyristors
•
Describe.the.basic.construction.of.a.DC.drive
•
Explain.the.significant.differences.between.1-.and.4-
quadrant.operation.in.a.DC.drive
•
Describe.features.and.operation.of.the.Siemens.6RA70.
DC.MASTER
•
Describe.the.characteristics.of.constant.torque,.constant.
horsepower,.and.variable.torque.applications
This.knowledge.will.help.you.better.understand.customer.
applications..In.addition,.you.will.be.better.able.to.describe.
products.to.customers.and.determine.important.differences.
between.products.
If.you.are.an.employee.of.a.Siemens.Energy.&.Automation.
authorized.distributor,.fill.out.the.final.exam.tear-out.card.and.
mail.in.the.card..We.will.mail.you.a.certificate.of.completion.if.
you.score.a.passing.grade..Good.luck.with.your.efforts.
SIMOREG,.SIMOREG.DC-MASTER,.SIMOVIS,.and.SIMOLINK.
are.registered.trademarks.of.Siemens.Energy.&.Automation,.
Inc..
Other.trademarks.are.the.property.of.their.respective.owners.
Totally Integrated Automation
and DC Drives
Totally Integrated
..
Totally.Integrated.Automation.(TIA).is.a.strategy.developed.
Automation
.
by.Siemens.that.emphasizes.the.seamless.integration.of.
automation.products..The.TIA.strategy.incorporates.a.wide.
variety.of.automation.products.such.as.programmable.
controllers,.computer.numerical.controls,.Human.Machine.
Interfaces.(HMI),.and.DC.drives.which.are.easily.connected.
via.open.protocol.networks..An.important.aspect.of.TIA.is.the.
ability.of.devices.to.communicate.with.each.other.over.various.
network.protocols.such.as.PROFIBUS-DP.
Siemens DC Drives
.
SIMOREG®.is.the.trade.name.for.Siemens.adjustable.speed.
DC.Drives..SIMOREG.stands.for.SIemens.MOtor.REGulator..
Siemens.DC.drives.are.an.important.element.of.the.TIA.
strategy..DC.motors.were.the.first.practical.device.to.convert.
electrical.energy.into.mechanical.energy..DC.motors,.coupled.
with.DC.drives.such.as.the.Siemens.SIMOREG.6RA70,.have.
been.widely.used.in.industrial.drive.applications.for.years,.
offering.very.precise.control.
Although.AC.motors.and.vector-control.drives.now.offer.
alternatives.to.DC,.there.are.many.applications.where.DC.
drives.offer.advantages.in.operator.friendliness,.reliability,.cost.
effectiveness,.and.performance..We.will.discuss.applications.
later.in.the.course.
