Brushless DC Drives

Brushless-DC Images

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 - MPU

Position 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:

  • Improve the position measurement accuracy
  • Minimize power dissipation inside the encoder case
  • Extend industrial temperature range
  • Realize EMC-compliant electrical interfaces with robust and reliable data transmission over cable lengths of up to 100m and more
