WHO WE ARE
Terra Modena Mechatronic (TMM) was founded in 2015 by Dario Calzavara with the mission of designing and manufacturing electrical powertrains with Axial Flux motors from 20kW to 400kW with energy by Lithium batteries for high performance boats.
We carry out projects with absolute confidentiality criteria and without using our Brand.
FUTURE ENERGY TECHNOLOGY
Together with a Group of international Researchers we are developing a clean new low energy nuclear technology the NEW ENERGY CLEAN TECH (provisional name) for private powerboats, yachts, superyachts and also for ferries, shuttles and commercial vessels for public use. The new technology will make a great contribution to the preservation of the seas by providing a source of clean and abundant energy avoiding the costs and the autonomy limitation of the current batteries. The Capex and operational costs will be dramatically reduced. More to come in April 2022.
NEW FACT
On Febrary 2022, Terra Modena Mechatronic signed an exclusive license agreement for the marketing and use of the NEW ENERGY CLEAN TECH (NECT) for maritime applications.
NECT will be presented at mid-April 2022 following a DEMO test at the Polytechnic University of Milan, Department of Nuclear Energy.
We are currently developing integrated electrical systems for several applications from private yacht to commercial vessel for public use.
TECHNOLOGY
MOTORS
A wide spectrum of electric machine can be proposed and specifically chosen for each application in order to guarantee the performances in terms of electric power, weight, mechanical coupling and cooling. We use Axial Flux three phases brushless machines.
SOFTWARE
The software of all the electronic devices is designed and developed in house, so we are responsible for the correct operation of the electronics. All the control logic of the system are specifically studied and designed according with each project specifics.
INVERTER
A large variety of controller is used. The power devices integrated inside the inverters use all the latest technologies available on the market, from Silicon power MOSFET or Silicon Carbide MOSFET transistor to Silicon IGBT bipolar transistors.
DASHBOARD
The multiple screens dashboard can be fully personalize following the customer requirements. The dashboard communicate with all the electronic system using the CAN protocol. All the information and Nav systems are available and can be shown to the driver.
IOT
WiFi expansion board for the remote control of the main battery information can be integrated inside the electronic system. The electronic circuit upload on the cloud the data from the battery pack and, in any minute, from each part of the word, it is always possible to monitor these information.
COMMUNICATION
The main protocol used is the Controller Area Network (CAN bus), which is perfectly compatible with the NMEA 2000 used in marine application. The node identification of all the data can be programmed in order to avoid address already used in the system with which make the interface.
BATTERY PACK
High voltage battery packs, from 115V up to 700V, are specifically designed for each application. We used Lithium Ion or Lithium polymer chemistry in order to guarantee the desired performances in terms of output current and energy stored related to the available spaces and weight target.
BMS
The BMS is integrated inside the battery pack. The voltage of each cell is constantly monitored and a passive balance system works for increase the stability of the system. The BMS verifies the temperature inside the pack, controls the flow of current, drives internal and external contactor and communicate by CAN bus protocol all the main information to the electronic system.
