Industrial Robotics Fundamentals: 5 & 6

Match the following

• Safety devices that are designed to prevent unauthorized access to hazardous areas.

• service robot

• A mobile robot that can move to a work area to perform the necessary

• dynamic performance

• A value that represents how quickly the robot can accelerate, decelerate, and come to a stop.

• interlocks

• The ability of a robot to provide precise points in the process of accurately locating parts.

• fixturing

• The maximum weight or mass of material a robot is capable of handling on a continuous basis.

• payload

Match the following

• Part of a dc motor that switches current flow.

• alternating current

• An action that occurs when energy is transformed into mechanical motion, heat, and etc.

• work

• A source of electrical power in which electrons flow in only one direction.

• direct current

• A source of electrical power in which electrons flow in one direction and then opposite.

• commutator

• The electromagnet in an electric motor that rotates within a magnetic field and creates torque.

• armature

Voltage generated as the armature of a dc motor rotates. This voltage opposes the voltage applied to the motor.

• series-wound dc motor

• counter electromotive force(cemf)

• commutator

• single-phase induction motor

The combination of subsystems that create a cohesive, operational process or unit.

• synthesized system

• field winding

• single-phase induction motor

• shunt-wound dc motor

A component of a servo system that produces controlled shaft displacements to achieve a precise degree of rotary motion.

• rotor

• servomotor

• single-phase ac motor

• armature

The stationary portion of a motor that includes the permanent magnets (or electromagnetic windings), a frame, and other stationary components

• stator

• universal motor

• torque

• detector

Components that transfer power from one point to another through mechanical motion that is used to do work.

• electromechanical system

• permanent-magnet dc motor

• counter electromotive force(cemf)

• load

Strength of the electromagnetic field within a dc motor; directly affected by changes in the field current.

• counter electromotive force (cemf)

• flux

• torque

• feedback

Components that turn a device on or off at a specific time or in step with an operating sequence.

• permanent magnet dc motor

• timing system

• single-phase ac motor

• transmission path

The process of converting alternating current (ac) to direct current (dc) power.

• rectification

• three-phase ac motor

• feedback

• indicator
