Abstract: Infineon’s iMOTIONTM IMC100 series is a highly-integrated, variable-rate IC that integrates the hardware and algorithms needed to control a permanent-magnet synchronous motor (PMSM), reducing motor system time-to-market and reducing system cost. Development costs, with field-controlled PMSM, flexible master interface for motor control commands such as UART, PWM or analog input signals, support for IEC 60335 ('Class B'), integrated scripting engine for flexible applications, mainly for refrigerators, Home Appliances, Motor Control, Pumps and Fans, and Other PMSM Drives. This article describes the iMOTIONTM IMC100 series main features, block diagrams, and application block diagrams, as well as evaluation board EVAL-M1-101T main features, block diagrams, schematics, bill of materials, and PCB design drawings. .
iMOTIONTM IMC100 is a series of highly integrated ICs for the control of variable speed drives. By integraTIng both the required hardware and algorithm to perform control of a Permanent Magnet Synchronous Motor (PMSM) they provide the shortest time to market for any motor system at The lowest system and development cost.
It also integrates multiple protection features like over- and Undervoltage, overcurrent, rotor lock etc. Powerful tools like MCEWizard and MCEDesigner reduce the implementation effort for a variable speed drive to a simple configuration of the MCE for the consistent motor.
The IMC100 series takes advantage of a new hardware platform that brings a comprehensive set of innovative analog and motor control peripherals.
The next generation of the MCE not only further improves the performance of the control algorithm but also adds functionality like sensor support for accurate rotor positioning, ready-to-use PFC algorithms as well as more and faster host interface options.
The IMC100 series is offered in several device variants ranging from single motor control to motor control plus PFC. All devices can be used in applications intendedintegrated safety acc. to IEC 60335 ('Class B'). With this wide application scope the IMC100 series Is the perfect choice for any highly efficient variable speed drive.
iMOTIONTM IMC100 main features:
• Motion Control Engine (MCE) as ready-to-use solution for variable speed drives
• Field oriented control (FOC) for permanent magnet synchronous motor (PMSM)
• Space vector PWM with sinusoidal commutation and integrated protection features
• Current sensing via single or leg shunt
• Sensorless operation
• Optional support for hall sensors (analog or digital)
• Optional boost or totem pole PFC control integrated
• Flexible host interface options for motor control commands: UART, PWM or analog input signal
• Support for IEC 60335 ('Class B')
• Integrated scripting engine for application flexibility
• Multiple package options
iMOTIONTM IMC100 Application:
• Refrigerators
• Home appliances
• Pumps, fans
• ...any other PMSM drive

Evaluation Board EVAL-M1-101T
EVAL-M1-101T is an evaluation-board as part of the iMOTIONTM Modular Application Design Kit. This board features and demonstrates Infineon's Advanced Motion Control Engine (MCE 2.0) technology for permanent magnet motors drive over the full speed range.
The evaluation board EVAL-M1-101T was developed to support customers during their first steps designing applications with running any permanent magnet motor via sensorless sinusoidal control.
The EVAL-M1-101T evaluation board is a part of the iMOTIONTM Modular Application Design Kit for drives (iMOTIONTM MADK). In order to run a motor, the mating power board is required to interface this evaluation board.
These boards can easily be interfaced through the 20-pin iMOTIONTM MADK ​​M1, or the 30-pin iMOTIONTM MADK ​​M3 interface connector. This board is equipped with 20- Pin M1 connector and is intended for single motor control only.
This evaluation board is designed to give comprehensible solutions of sensorless control of permanent magnet motors over the full speed range. It provides a capable of 3-phase and type 3 of 2-phase modulation, a micro- USB connector and on board debugger isolated by Digital isolator, and UART interface.
So happy to know that 11th laptop is ranking the No.1 position in 2022 custom market. You can see intel core i3 11th generation laptop,Gaming Laptop i5 11th generation, laptop price i7 11th generation, etc. At this store. Maybe you will ask why 11th gen gaming laptop is so popular and welcome, mainly reason is its competitive cost and high performance. Intel i7 11th Generation Laptop cost is similar as intel i7 10th gen laptop, but performance is much better than 10th one. Besides, 12th laptop is arriving in lot at the end of 2022 at custom laptop market, price is will much competitive at that time.
Whom this Gaming Laptop is more suitable to? Of course, heavier tasks workers, no matter office jobs, education tasks, or others. However, if your clients focus more powerful cpu and performance, i7 16gb ram 4gb graphics laptop or 15 Inch Gaming Laptop with 10th cpu and 2GB graphics also alternatives.
You can contact us directly to get get right and valuable information fast. Will try our best to support every clients no matter quantity you take.
