Electronics for Powertrain Applications
Mobility is an important factor for the global economy
Sophisticated engine management and strict exhaust gas standards require increasingly individual sensor solutions, highly efficient motor controls for electrified auxilliary units and innovative technologies. We are at home in this market and offer you the appropriate solution for your project.
Our engineers understand optimal control means: higher efficiency, lower emissions and an increase in driving pleasure
In order to handle resources in a responsible way and to protect the environment, it is necessary to measure precisely, even at a low rotational speed, immediately when the engine of a vehicle has been started.
Detecting rotational speeds without loss enables optimal engine control resulting in improved driving characteristics and low emissions.
Special features
- Working range up to 3 mm
- Temperature range -40 °C to +160 °C
- Protection rating up to IP 69
- True power on
- Detection of direction
Example

Rotor Position Sensor – Electric Motors
SPINpad - high-speed rotation and positioning technology
The new inductive high-speed rotation and position technology (SPINpad) has been developed in accordance with the requirements ISO 26262 and enables the accurate detection of speed and rotary position, especially for sensors in the engine and vehicle mount portion of the drive train.
An inductive high speed rotor position sensor (SPINpad sensor)
A combination of high accuracy and fast response time is required for rotor position sensors in the electric motors of hybrid or electric vehicles. This allows the control unit to drive the motor optimally, and leads to a reduction in energy consumption and an increased range of the vehicle.
KYOCERA AVX has developed a new high speed position sensor to meet these requirements. First prototypes of this new sensor have demonstrated market leading performance. This technology can be used in other applications where accuracy and response times are critical (for example, electric power steering), and is also capable of making an additional velocity measurement, which could be used in active suspension systems.
The basic structure of the SPINpad sensor is similar to KYOCERA AVX‘s mature and proven Autopad® technology. However, the SPINpad sensor uses one coil as a transmit coil and two coils as receive coils.
Typical applications
- Traction Motors for any application (e.g. BEV, PHEV, HEV and MHEV or industrial applications)
- Electric Compressor
- Steer by Wire
- Electric Turbocharger/Supercharger
- Brake Booster
Special features
- Flexible designs, can be matched to motor pole-pairs giving positional accuracy < 0.5deg electrical
- Different targets available
- Signal immediately after power on
- High speed up to 100,000 rpm
- Ready for ASIL C (D) or with redundant measurement ASIL D (D)
- Immune to low frequency magnetic fields
- Small package size, flat design
- Temperature range: -40 °C to 160 °C

Motor Control Unit (MCU) for Brushless DC Motor (BLDC Motors)
A customer-specific control unit from KYOCERA AVX (Salzburg) provides significant advantages for integration into the electric motor and into the existing installation space. The modules contain all the necessary components for the control of a brushless DC motor (BLDC motor). Their design is adapted, via the selection of the electrical components and the mechanical fasteners, also to the smallest installation space requirements and coordinated perfectly with the respective application. The comprehensive know-how of several product generations is used via sophisticated thermal and mechanical simulation. Each control unit meets the requirement of a perfectly coordinated solution with regard to space, reliability, manufacturability and cost efficiency. The specially developed contact and connecting elements also contribute to this and permit optimal connection to the external connector and, besides the mechanical reliability, provide an important cost advantage. Increasingly shorter development times in the automotive industry are achieved via specially developed platforms for hardware and software solutions. In that way it is possible to make the first prototype available within a few weeks and to successfully implement a closely coordinated project schedule as far as series production. All the platforms can be adapted at any time to the needs of other applications and automobile manufacturers. This applies to the power (30 W – 10 kW), to the on-board voltage (12 V – 810 V), and to the required communication (PWM, LIN, CAN) with the control unit.
Special characteristics
- High temperature range (-40 to + 150 °C)
- High performance in a small installation space
- High vibrations permissible, attachment to combustion engine and transmission possible
