Smart Electric Motor: Technology Innovation as a Key Enabler of Energy Efficiency
1. Current Enviroment
Industrial world — as we know it — keeps spinning thanks to electric
motors. According to International Energy Agency (IEA), electric motors are
responsible for more than half of the global electricity use. Another important
fact presented by Asian Development Bank (ADB)
study says that share of the Asia-Pacific region on
global energy consumption is set to increase to 56% by 2035. Growth in
electricity use is led by industrial motors (notably in China).
Electricity consumption levels predicted to increase deserve energy efficient
and sustainable approach, smartening up of electric motors and also efforts for
2. Push, Push, Push
Governments around the world are pushing minimum energy performance standards
initiatives, regulations, policies. Notable push comes from the side of
financial and banking institutions — providing loans, number of support
schemes and programs, credit lines for large scale energy efficiency deployment
projects. Customer push — demand for intelligent IOT enabled electric
motor — comes from repeated and often frustrating experience of production
downtime occurrence and their effect on company’s bottom line. Manufacturer
push comes from the motivation not only to be able to supply the best in class
electric motor, but also increase its efficiency and provide predictive
maintenance of a motor at their customer production facilities.
Last but not least — there is also environmental aspect — that requires
immediate action. Electric motors emit a total of 6,800 metrics tons of
carbon dioxide in a year. A transition to energy-efficient motor systems
would reduce the global electricity demand for electric motors by around 20% to
30% by 2030.
3. Technology Push
Connecting piece of all initiatives is the technology. Innovation. We at
RVmagnetics are bringing the novel technology — the smallest passive
sensor in the world. Thank to its size — our passive contactless
sensor — MicroWire — is able to maximize motor
efficiency. We can achieve that by measuring real time temperature inside of the
motor — allowing us to be aware of Curie temperature limit and get closer to
the limit without causing irreversible damage to the motor itself. Result is the
intelligent, more efficient solution.
sensor — passive unpowered element — enables realtime temperature
detection from inside of an electric motor. Powered part — sensing head —
conducts the measurement from the outside of the motor casing / chassis —
needs to be within a maximum range of 10 cm / 3 inch from the Microwire
sensor. Sensing possibilities include temperature, vibration, tensile
stress, rotation speed and position of rotor vs. stator.
Significant benefits include performance monitoring, optimizing predictive
maintenance, avoiding risk of interrupting production, maintenance optimisation,
production downtime reduction, real-time motor health monitoring (temperature,
vibration …). Increases efficiency and effectiveness by maximizing the
potential of physical limits that can also later lead to motor / chassis size
reduction and so much desired power consumption decrease, motor burnout
prevention and much more.
In a nutshell: you can achieve higher output with your current engine, or use
smaller motors to achieve the same output as before, all with the same level of
safety and minimum of engine design changes.
4. Turning Back the Time?
“If the world is to turn today’s emissions trend around, it will need to
focus on the emissions that are “locked in” to existing systems says World Energy Outlook 2019.
The most challenging part is to smarten up electric motors that are already
in use. Those, that client already uses in every day production. With
RVmagnetics MicroWire technology you won’t need to change your existing
industrial design. Simple plug & play solution, in most cases implementable
during scheduled maintenance.
5. Win for All Stakeholders
Progress and effects of CO2 emissions, reflecting on climate change are
enormous and unpredictable. One thing we know for sure is that emissions are not
benefiting the stability of global climate. Solution we present also reduces the
need of power capacity required for sensing as such.
On one hand — key economic benefit for the client having installed the
smart sensor is predictive maintenance — significant reduction of production
downtimes. On the manufacturer side — better planning of maintenance / repair
and replacement activities.
While all the rest of the world may just breathe the cleaner air…
