I. Brushless DC Motors (BLDC) and Drive Solutions

ADI’s brushless DC motors (BLDC) and accompanying drive solutions eliminate the mechanical commutation structure of traditional brushed motors, operating instead on the basis of electronic commutation technology. This completely resolves issues such as brush wear, electrical sparks, excessive noise and short service life, making them the preferred choice for high-performance, long-life motion applications. ADI has introduced integrated drive and control chips for BLDC motors, achieving a high degree of integration for motor drive, current sensing and closed-loop control, thereby significantly simplifying the system architecture.

A prime example of these core products is the TMC9660, a highly integrated monolithic motor controller and gate driver IC. It is compatible with three-phase PMSM/BLDC motors, two-phase stepper motors and standard DC motors, supporting coil currents of up to 5 A RMS and a wide voltage range of 8 V, making it suitable for a variety of low-voltage brushless motor applications. The chip incorporates a complete FOC (Field-Oriented Control) algorithm and supports a wide range of PWM carrier frequencies from 2 kHz to 100 kHz, making it suitable for a variety of devices, including low-inductance air-core cup motors and high-speed industrial brushless motors. It also integrates lossless current sensing and a three-loop closed-loop control system for torque, speed and position, eliminating the need for complex peripheral circuits and programming, thereby significantly shortening product development cycles.

Leveraging ADI’s proprietary motion control technology, the BLDC driver solution delivers exceptional operational stability, with jitter-free operation at low speeds, rapid response at high speeds and smooth power output, whilst achieving energy efficiency far surpassing that of traditional driver solutions. It is widely used in applications with stringent requirements for service life, precision and energy efficiency, such as dexterous hands for humanoid robots, industrial servo mechanisms, fans in smart home appliances, precision medical transmission equipment and portable new-energy actuators.

II. Stepper Motors and High-Performance Driver Solutions

ADI’s stepper motor products are characterised by high-precision microstepping, low-noise operation, high integration and strong immunity to interference. Addressing industry pain points associated with traditional stepper motors—such as open-loop loss of step, high noise levels, insufficient torque and low control accuracy—ADI has developed dual series of driver solutions (open-loop and closed-loop) that balance cost-effectiveness with high performance, making them suitable for small-to-medium-sized precision positioning applications.

Key representative products include high-end driver ICs such as the TMC2241, TMC2240 and TMC5240. The entire range incorporates ADI’s proprietary StealthChop2 silent chopping technology and a 256-microstep microstepping algorithm, enabling exceptionally smooth motor operation. This completely eliminates the low-frequency resonance and whining typical of traditional stepper motors, whilst significantly reducing operating noise. The TMC2241, in particular, is a high-voltage intelligent stepper driver IC that integrates a 65V/3.0A high-current H-bridge and lossless current sensing (ICS) functionality. It eliminates the need for external sampling resistors, simplifying the hardware structure whilst enhancing current detection accuracy.

The TMC5240 further integrates a dedicated motion controller, enabling integrated control of trajectory planning, position closed-loop control and stall detection. Compared to traditional discrete solutions, this saves over 60 per cent of PCB space and improves operational efficiency by nearly 20 per cent. At the same time, ADI’s closed-loop stepper solution can verify the rotor position in real time and detect stall and loss-of-step issues, achieving control accuracy and torque performance approaching that of servo motors whilst retaining the cost-effectiveness of stepper motors.

The product is widely used in precision positioning applications such as 3C automation equipment, precision printing equipment, security PTZ cameras, smart warehouse conveyance systems, small automated manipulators and medical diagnostic equipment.

III. Integrated Smart Motor Solutions

ADI’s smart motors are integrated motion units combining drive, control and sensing functions, representing an evolution of traditional motor architecture. They break away from the conventional discrete configuration of ‘motor body + driver board + controller + sensor’ by highly integrating drive chips, motion control algorithms, position sensing, fault diagnosis and communication interfaces. This enables intelligent, compact and modular motors, making them core motion components for Industry 4.0 and smart edge devices.

Centred on a fully integrated servo drive and control architecture, this series of solutions supports a wide range of motor types, including PMSM and BLDC, as well as servo motors. It features built-in automatic motor parameter recognition, RAMP trajectory planning and real-time fault diagnosis (overcurrent, overvoltage, stalled motor and overheating protection), enabling high-precision intelligent motion control without the need for complex programming. It also supports SPI daisy-chain cascading, allowing dozens of smart motor units to be connected in series via a single bus, thereby greatly simplifying the wiring and control system architecture of multi-axis synchronised equipment.

Compared to traditional motor solutions, ADI’s smart motors offer three key advantages: firstly, a highly integrated, minimalist design that eliminates the need for numerous peripheral components, resulting in smaller equipment footprints and lower failure rates; secondly, intelligent adaptive control that automatically adjusts torque and speed in response to load variations, making them suitable for dynamic load scenarios; and thirdly, digital interaction capabilities that support real-time data upload, remote parameter debugging and operational status monitoring, thereby meeting the IoT operation and maintenance requirements of smart devices.

They are primarily used in high-end intelligent motion applications such as humanoid robots, smart automated production lines, precision servo drives, drone propulsion systems, smart medical actuators and high-end smart home actuators.

IV. Motor Encoders and High-Precision Sensing Solutions

Motor encoders are the ‘sensing core’ of motor motion control, responsible for real-time acquisition of motor rotor position, speed and angular displacement data. They provide precise feedback for closed-loop control and directly determine the precision of motor control. ADI focuses on the field of high-precision motor sensing and has launched a comprehensive suite of solutions for encoder signal conditioning, sampling and processing, optimised specifically for motor motion applications. These solutions are compatible with both incremental and absolute motor encoders.

The flagship device, the AD7380, is a high-precision sampling ADC designed specifically for encoders. It features an ultra-compact 3mm × 3mm package, making it suitable for encoders with confined PCB layouts. The chip features an ultra-high dual-channel synchronous sampling rate of 4 MSPS and 16-bit high-precision sampling accuracy, enabling it to fully capture the subtle variations in the encoder’s sine and cosine signals. Combined with on-chip oversampling technology, this significantly enhances position resolution accuracy and eliminates position sampling lag and data distortion during high-speed operation.

ADI’s encoder solutions offer high immunity to interference, high stability and high resolution, making them suitable for complex industrial electromagnetic environments. They effectively suppress electromagnetic interference during motor operation, ensuring the real-time nature and accuracy of position and speed feedback data, and providing core data support for high-precision closed-loop control of BLDC motors, servo motors and closed-loop stepper motors. At the same time, they are accompanied by comprehensive signal conditioning and power supply solutions, enabling a minimalist design and stable operation of the encoder sensing system.

These solutions are widely adopted in industrial servo motors, precision stepper motors, robotic joint motors and motors for high-end automation equipment—all of which demand extremely high standards of positional accuracy and rotational speed stability.
