Designed for home appliances, the GD32M531 32-bit microcontrollers were launched at Embedded World by GigaDevice. Based on an Arm Cortex-M33 core, operating at 180MHz, and integrates peripherals to control and optimise dual motor performance, with power factor correction. It also integrates DSP extensions and a floating-point unit. It is equipped with 256kB flash, 64kB Data-Flash, and 32kB SRAM, enabling it ...
There are easier-to-use alternatives to the thyristor (aka SCR) based mains fed motor controllers used to control ‘180Vdc’ brushed electric motors. These are mosfet choppers, but they tend to cost over £100 and are often poorly documented as they are made as drop-in replacements for treadmill motor controllers such as the MC2100ELS. Interfacing to them can also be tricky as ...
Melexis has put three processor cores into its very-application-specific motor driver for automotive air vent flaps. MLX81350 is the company’s fourth-generation of automotive motor driver with LIN communication, delivering up to 5W (0.5A) per motor. For a seemingly simple application, this IC packs a lot of technology. Firstly, it is built on a high-voltage SOI (silicon-on-insulator) process, its is designed ...
EPC has designed a GaN-based motor driver for robot limb joints. EPC91120, as it is know, is a evaluation board implementing a three-phase brushless dc motor driver in a 32mm diameter circular footprint designed to be built directly into robotic motor assemblies – particularly with the Unitree A1 motor, which is part of a robot dog. “We used the Unitree ...
Wonderland’s current pwm to voltage converter mini-project is to interface a modern grblHAL cnc board with a late 1990s era thyristor-based motor control board in an milling machine. The board appears to be both sophisticated and flexible – for example, it can use armature voltage or a tachometer for speed feedback, it has several different input options to set the ...
Infineon has created a pair of motor controllers for small automotive electric motors. “The three-phase TLE995x for brushless dc motors is ideal for pumps and fans in thermal management systems, while the two-phase TLE994x for brushed dc motors targets comfort functions such as electric seats and power windows,” according to the company. “All devices comply with ISO 26262 ASIL B ...
Renesas has introduced 1GHz Arm Cortex-M85 microcontrollers, with or without a 250MHz Cortex-M33 co-processor. “The new MCUs deliver 7,300 Coremarks of compute performance. The optional Cortex-M33 core can act as a housekeeping MCU, executing system tasks while the high performance core stays in sleep mode,” said the company. “They are built on the same high-speed, low-power 22-nm ULL process used ...
