To size a electric motor for a
particular drive application the designer must first
analyze the mechanics of the drive application. The
following must be determined:
-
Friction of the bearings, or other
mechanical elements.
-
The weight or load to be driven by the
electric motor.
-
Inertia of the mass to be moved or
controlled. Acceleration and deceleration forces
should be analyzed.
-
Mechanical system type and number of
linkages.
Friction -The friction may be determined
by estimation, component specification or by measuring by
use of a torque reading device or mechanism.
Weight or Mass - The mass may be
calculated using 3D CAD, specification or direct
measurement.
Inertia - Inertia is the force
required to accelerate or decelerate a mass. Inertia
is used to calculate the motor torque required to operate
the mechanical system.
Mechanical System - There are roughly four
categories of mechanical drive systems
-
Direct drive
-
Gear drive
-
Tangential drive
-
Lead-screw or worm-gear
