Conntek achieves new best values ​​in magnetic position sensors and enables new fields of application.

The KTM5900 can replace optical encoders with the incremental ABZ output, e.g. for motor feedback systems. It is suitable for both on-axis and off-axis applications and therefore offers a high level of flexibility in mechanical design due to its very small design.

The KTM5900 has a 12-bit multi-pole pair counter for up to 4096 pole pairs.

The KTM5900 supports versatile output modes including a 36 Mbps SPI absolute angle output, a programmable ABZ quadrature incremental output with up to 65536 edges, a programmable UVW output for up to 256 pole pairs and a PWM output. Other features of the KTM5900 include automatic linear and nonlinear calibration, Z signal calibration, absolute position synchronization for multipole applications, automatic TMR adjustment for orthogonal signal calculation, and programmable operational amplifier gain. Additionally, the KTM5900 features two industry-leading 2MHz 16-bit SAR ADCs to improve performance and precision.

Particular emphasis was placed on functional safety in the KTM5900. There is an 8-bit CRC verification for the SPI transmission of the angle values ​​and many self-diagnosis alarm functions are implemented.

A key advantage of the KTM5900 is its ability to automatically detect non-linear errors during normal operation and correct them with just a press of a button or an SPI command. In addition, the KTM5900 features a 256-point correction table that allows the user to improve absolute accuracy by storing non-linear error corrections from optical encoders in the KTM5900.

Using a single-pole magnet, both the one-button self-calibration and 256-point error correction table can achieve excellent INL ≤ 0.025°.

High resolution inductive encoder

Cambridge IC presents the CAM622, a new high-resolution resonant inductive encoder IC with ABN output.

Based on the existing inductive resonator position detection technology, Cambridge IC has developed a new sensor processor with a scalable high-resolution quadrature encoder output (ABN/ABZ). Both the sensor and the position target are made of easily available circuit board material (e.g. FR4) with printed coils. The sensor board has electrical connections to CAM622 circuitry. The target is passive and contactless. Only two small capacitors must be fitted here to build an inductive resonator. This design enables an extremely compact construction.

The CAM622 sensor processor is embedded inside a customer’s product.  It includes an SPI interface used for programming parameters including the number of AB cycles, and position of the N pulse. The maximum number of AB cycles is 16384, to yield 65536 edges per revolution and 16-bit resolution.

The CAM622’s SPI interface may also be used to read measurement results directly, including absolute position and diagnostics.

No calibration is necessary. The CAM622 measures position 33,000 times per second, at rotation rates of up to at least 60,000 rpm.

For evaluation the CAM622 ABN Board is available. It connects to a Windows PC via an adapter for programming and evaluation. It includes a regulator and line driver for stand-alone differential ABN operation from a 5V supply.

Wolfspeed and MEV – Partners in Silicon Carbide (SiC)

MEV Elektronik has been working with its partner Wolfspeed for many years. Wolfspeed’s SiC MOSFETs, Diodes and Modules have faster switching speeds and consume less energy than conventional silicon solutions at comparable prices. More and more application areas are coming into focus. For example: Low voltage motors, Servo motors, Heat Pumps, Air Conditioners and More …

Wolfspeed silicon carbide enables embedded motor drives

Electric motors, including industrial low voltage drives, account for more than 50% of all electricity used in industry globally. Traditionally, industrial low voltage motor drives were designed with the motor and drive in separate housings and connected by a long cable, resulting in poor motor reliability or increased cost from needing output filters, wasted power and lower overall system efficiency.  ​

Today silicon carbide is enabling a shift to embedded motor drives where the drive and motor are combined into one smaller unit. Combining motors and drives can reduce overall system cost by 20-40% and improve drive efficiency by up to 2.6% so motor manufacturers can achieve IE3 and IE4 efficiency standards.

Design embedded servo drives with Wolfspeed Silicon Carbide​

Designing servo drives with Wolfspeed silicon carbide enables smaller, more efficient and power dense embedded servo drives. Silicon carbide can also overcome the thermal challenges that plague IGBTs, further reducing the size of drives and resulting in longer system life.

Optimize servo drive systems with Wolfspeed 650 V MOSFETs​

Wolfspeed 650 V silicon carbide MOSFETs allow servo drive designers to optimize systems for maximum efficiency at a reduced size and cost. For example, in an 11 kW, 8 kHz system upgrading to a semi-bridgeless Totem Pole-PFC and replacing IGBTs in the inverter with drop-in silicon carbide MOSFETS yields:​

Redesigning the PFC using a bridgeless totem pole topology and upgrading the inverter with silicon carbide MOSFETs improves efficiency even more to 2.4%. ​

When compared to high-speed, soft-switched IGBTs, Wolfspeed 650 V MOSFETs offer drastically lower conduction losses and almost no switching losses, significantly improving the performance of embedded industrial motor drives.

Silicon carbide enables more efficient heat pumps and air conditioners with minimal redesign​​

Today, heating and cooling systems consume more than 50% of all energy produced globally. Increasingly stringent energy efficiency standards including the American SEER ratings; ESEER and SCOP levels in Europe, the middle east and Africa; and China’s GB21455 standards are all targeting reducing the impact heating and cooling have on our power grid and on the warming planet. ​

Switching from traditional silicon to Wolfspeed Silicon Carbide devices can increase a heating or cooling system’s efficiency while reducing overall unit size and cost of ownership. Silicon carbide enables increased SCOP levels, superior thermal performance and less audible noise (>20 kHz frequency).

Model silicon carbide efficiency with SpeedFit™​

Maximize heat pump and air conditioning efficiency when you simulate with SpeedFit Design Simulator, the first step to selecting the right devices for your design. Our online simulation tool offers an easy-to-use interface for evaluating Wolfspeed’s silicon carbide MOSFETs, diodes and power modules many power topologies.
