Motor Drive and Control TI’s motor drive and control system solutions get your industrial motors spinning faster, safer and greener.Texas Instruments provides a broad range of analog products, digital controllers and software to precisely control the position, velocity and torque of mechanical drives. Motor control and drive solutions are available for small drives including solenoids, DC or brushless DC and steppers; and for larger drives such as AC-open loop and closed loop systems that utilize much higher voltages, typically hundreds of volts.
AC Inverter & VF Drives - MCUTI solutions for variable speed drives help customers design hardware for their drives with optimized performance, drive power rating and operating voltage. Our reference designs help evaluate multiple sub-system designs to decide on a suitable hardware architecture with ready-to-use circuits with enhanced performance, isolation, safety, and reliability standards. These circuits are tested for electrical, thermal and EMC requirements as per IEC61800 to help customers quickly evaluate products and accelerate design cycle time. Sub-system reference designs span across all functionalities of the variable speed drive including:
TI offers variety of MCUs with different processing capabilities, isolation products with basic and reinforced isolation, precision operation amplifiers and power supply solutions that provide flexibility to customers on arriving to an optimum partitioning of the drive with single or dual controller.
Brushless DC Drives
The brushless DC (BLDC) motor can be envisioned as a brush DC motor turned inside out, where the permanent magnets are on the rotor, and the windings are on the stator. As a result, there are no brushes and commutators in this motor, and all of the disadvantages associated with the sparking of brush DC motors are eliminated. From single chip motor controller to gate driver that can be paired with microcontroller and MOSFETs, TI’s flexible BLDC motor drive and control portfolio enables different levels of acoustics, torque and efficiency performance ideal for industrial, automotive and functional safety applications.
Position Encoders & Resolvers - MPUPosition encoders are either with incremental or absolute position measurement and typically leverage optical or inductive/magnetic sensing with integrated semiconductor components for power management, analog signal conditioning and embedded signal processing and electrical interface. Either analog, digital, or a hybrid analog and digital electrical interface is used depending upon the encoder type and vendor with cable lengths of 100m and more. Our solutions for incremental as well as absolute position encoders can help:
Industrial Brushed DC Drives
TI products and reference designs for brushed DC drives can be included in a complete system addressing the challenges of achieving a simple solution with robust protection features like overcurrent shutdown, pre-driver faults and over temperature to protect power devices. Our reference designs provide ready to use circuits which are tested for electrical, thermal and EMC performances helping customers quickly evaluate products and accelerate their design cycle time. Sub-system reference designs span across all functionalities of the brushed DC drive including:
Industrial Stepper Drive
TI solutions and reference designs help solve design challenges of stepper drives such as optimum performance, efficiency, high integration, minimum board space and protection. The reference designs provide ready-to-use circuits which are tested for electrical, thermal and EMC immunity performances helping customers in quick evaluation of products and accelerating design cycle time. TI solutions include gate drivers with various topologies and power FETs with low gate charge and low RDS(on) enabling flexible architectures for five-phase, three-phase and two-phase bipolar or unipolar stepper drives with high-efficiency and flexible voltage and current ratings. Our integrated stepper drivers provide flexible PWM interfaces to implement custom specific control algorithms with TI’s embedded microcontrollers, as well as step/direction interfaces with integrated micro-stepping indexer and accurate phase current control to meet various architecture requirements. TI analog and embedded solutions help solve challenges with accurate and EMC compliant current, voltage and position feedback sensing, as well as EMC compliant, isolated communication interfaces to help customers with time-to-market.
