The AMT49406 is available in a 24-contact 4 mm × 4 mm QFN with exposed thermal pad (suffix ES) and a 24-lead TSSOP with exposed thermal pad (suffix LP). Closed-loop speed control is optional, and RPM-to-clock frequency ratio is programmable.Ī simple I2C interface is provided for setting motor-rated voltage, rated current, rated speed, resistance, and startup profiles. Motor speed is controlled through analog, PWM, or CLOCK input. The device optimizes the motor startup performance in a stationary condition, a windmill condition, and even in a reverse windmill condition. The AMT49406 is ideal for ceiling fans, pedestal fans, bathroom exhaust fans and home appliance fans and pumps.Ī field-oriented control (FOC) algorithm is fully integrated to achieve the best efficiency and acoustic noise performance.

Additionally, all controls and designs with the MP6570 can be easily done with MPS? GUI software.The AMT49406 is a 3-phase, sensorless, brushless DC (BLDC) motor driver (gate driver) which can operate from 5.5 to 50 V-Allegro’s first QuietMotion solution. The MP6570 has non-volatile memory, which is flexible for parameters programmed through a standard I2C interface. It has up to 500kHz data refresh rate and 10-bit position resolution, ideal for BLDC and PMSM motor controls, especially in application (i.e.: high-speed control and high-position accuracy servo). Standard features include auto-tuning, s-curve profiling, FOC (Field Oriented Control), high/low switch signal control, direct encoder & pulse & direction input, and much more.

The on-chip angular sensor uses MPS? high-speed and accuracy angular sensor for rotor position and speed feedback. The MC58113 series of ICs are part of PMDs popular Magellan Motion Control IC Family and provide advanced position control for step motors, BLDC, and DC Brush motors alike. With the FOC algorithm, the motor 3-phase winding voltage is modulated through the SVPWM module, which has up to 12-bit resolution at 40kHz switching frequency. The motor 3-phase current is sampled and digitalized to the current/torque control loop by a 10-bit ADC. The reference command comes from the digital interface input or external single-input signal either in clock or PWM input. The MP6570 can be operated in position control, speed-control mode, or torque-control mode. Thus, two control loops exist in the BLDC motor control system, which are current and speed control loops 3. The torque and flux control can be achieved by means of field oriented control (FOC) which is sometimes called decoupling control or vector control. Field Oriented Control (FOC) of BLDC motors - Field Oriented Control (FOC). BLDC motors have the speed and torque control characteristics similar to DC motors. The FOC control is used to achieve high performances of motors and provides higher dynamic response, lower torque ripple, and higher efficiency. Our intuitive development tools and common motion architecture make design. The MP6570 can be used in applications with 3-phase PMSM and BLDC motors. In the case of induction or brushless drive systems, the FOC requires a speed sensor, such as shaft-mounted tachogenerator, resolver, or digital shaft position encoder, for obtaining speed information, which spoils the ruggedness and simplicity of. Field-oriented control provides maximum torque per amp or field weakening control for various motor types, including inductance machines, permanent magnet synchronous machines (PMSMs), and brushless DC (BLDC) motors. The MP6570 is a high-performance controller using a field-oriented-control (FOC) method and an accurate, on-chip, angular sensor. The field-oriented control (FOC) concept is widely used for high performance control of AC motors.
