Integral Motor-drive System

Abstract
Optimising industrial motor driven applications, when coupled with best practice
motor management, can deliver more than 57% energy savings. The need for
variable speed drives and their advantages are very well known, but
unfortunately, the integration of the knowledge of efficient electrical motors and
advantages of power electronics engineering is not well practiced by industries.
It has also been observed that further saving can be achieved by integration of
efficient systems. In this paper, a compact integral motor-drive unit built to
operate in arduous industrial environments with optimised power consumption
and best practice motor management under different load conditions is proposed.
Reduction of the losses in the system provides higher efficiency and further
savings to overcome heat without requirement of any additional cooling system.
The critical issues such as space limitations within the existing spatial
dimensions of motor, management of heat transfer from the motor to the
sensitive drive control unit, management of vibration transfer to the sensitive
drive control unit, management of electromagnetic interference within the unit
and externally, management of other environmental effects on the sensitive drive
control unit have been considered and discussed in this paper.
Keywords: electromagnetic interference, energy saving, integral motor, motor
management, sensitive electronics.
1 Introduction
Today, electric motors and controllers are essential parts of most equipment. The
current engineering design practice is based on viewing the motors and their
