INVEOR M – smart, robust, durable

Imagine a motor-mounted variable frequency drive controlling the air-conditioning compressor of an urban bus. A simple task for a drive controller. But now think about how this bus travels its route 24 hours a day, all year round. Including accelerating, braking and potholes. You will realise that, very quickly, the simple task needs a smart solution, packaged in a robust and durable variable frequency drive. 

The KOSTAL INVEOR M frequency inverter is our solid drive controller, which can be optimally adapted to the needs of our customers thanks to its modular concept. It is available as a three-phase and a single-phase variable frequency drive in five sizes from 0.25 kW to 22 KW, making it highly versatile. The robust aluminium housing supports its flexibility such that the INVEOR M can also easily meet the requirements of mobile applications, such as in cooling or braking units.

Thanks to the motor-mounted design, the INVEOR M does not require a control cabinet or supply cables, which reduces the EMC emissions and acquisition costs. At the same time, the tidy and clean look ensures a smart overview. And the same is true across all areas of application. Single-phase or three-phase? Choose the model with the voltage to suit you: the 1-phase variable frequency drive with 230 V or the 3-phase variable frequency drive with 400 V.

Features of the INVEOR M

  1. Robust aluminium housing: Avoid costly failures and, thanks to the sturdy design, control your speeds in a reliable and low-maintenance manner – even in mobile and heavy-duty applications.
  2. Low maintenance and durable: The fanless design up to 7.5kW and the smart DC link concept with film capacitors reduce susceptibility to faults and ensure a long life cycle.
  3. Various application circuit boards: Tap into its diversity and adapt the INVEOR M to your needs – with additional safety functions and fieldbus interfaces.
  4. Adapter plates for all motor types: The innovative adaptation concept with an extensive range of standard and motor-specific adapter plates allows the device to be used with almost every motor on the market.
  5. INVERTERapp: Commissioning - parameterisation - monitoring, you can now do all this easily and wirelessly via a Bluetooth connection from your mobile phone or tablet.

The INVEOR M variable frequency drive's control process


The motor-mounted INVEOR M frequency inverter is available in five sizes covering a power spectrum from 0.25 kW to 22 kW. It therefore provides the appropriate power for each of your areas of application – and always with sufficient overload capacity.

Thanks to the field-oriented sensorless control, the INVEOR M also attains improved start-up torques and higher efficiency. This increases the control quality of the speed control for your electric motors and therefore your productivity. And at lower cost since there is no need for the maintenance-intensive encoder feedback.

INVEOR M performance parameters 

  • 150 % overload: Use 150 % overload for up to 60 seconds if required and meet power peaks with ease.
  • Speed setting range of 1:20: Control your three-phase motors precisely and accurately – thanks to an optimised speed setting range and very good control quality. 
  • Control of synchronous and asynchronous motors: take responsibility for the speed control of all your asynchronous and synchronous motors – up to efficiency class IE4.
  • 0.25 kW - 22 kW power: Choose the variable frequency drive with the right power for you from five assemblies – and only pay for what you really need.

Of course, with the INVEOR M you also benefit from easy commissioning thanks to automatic motor identification (SelfCom) as well as special application-specific functions such as blockage detection and dry-running protection. With the SelfCom function, the motor is measured at the push of a button and provides high-quality control parameters, eliminating the need for time-consuming calibration on the test bench. With its STO function, which leads to 
immediate and safe shutdown of the power output stages when activated, the INVEOR M achieves Sil3 PLD certification. The integrated soft PLC allows access to all internal process variables and at the same time enables the implementation of customer-specific functions. A wireless connection via Bluetooth offers the possibility of convenient commissioning, parameterisation and monitoring via app.

INVEOR M variable frequency drive communication

The KOSTAL INVEOR M variable frequency drive has an extensive choice of interfaces and communication options. This means you can integrate it into all your processes and continue to use your previous internal fieldbus system without any problems.

Interfaces of the INVEOR M variable frequency drive:

  • CANopen, PROFIBUS, PROFINET, SERCOS III, EtherCAT (optional): Take advantage of the diversity of our various application circuit boards. And equip the INVEOR M variable frequency drive with the interfaces that suit you, in addition to the standard Modbus RTU.
  • Bluetooth (optional): Control the INVEOR M frequency inverter via Bluetooth if you wish. Either permanently installed or as a plug-in solution.

Operating and observing the INVEOR M variable frequency drive

The KOSTAL INVEOR M drive controller can be adapted to all your operating preferences. Even app-based mobile control is possible – for the greatest possible flexibility. 

Decide for yourself which operating functions you want to use:

  • Potentiometer and foil keypad
  • Man-machine interface (MMI) in the cover or with cable
  • Wall-mounted touch panel
  • KOSTAL INVERTER pc software

Motor adaptation of the INVEOR M variable frequency drive

The KOSTAL INVEOR M variable frequency drive is suitable for all common motor types thanks to numerous adapter plates. Be it via a standard adapter plate with individual bores, with intermediate adapter or preconfigured precisely to your needs: with the KOSTAL motor adaptation concept, you can enjoy the benefits of a motor-mounted INVEOR M variable frequency drive with every electric motor. 

And if you do not have enough space within an application: with the adapter plate for wall mounting, the INVEOR M can also be mounted on the wall close to the application. For short distances and time savings.
