Industrial Drives

industrial drives

Electric motors are used in large numbers in many industrial environments to perform a wide array of tasks and functions such as turning shafts or driving pumps and fans. Depending on the mission profile and control technique, various types of motors including universal, brushed or brushless DC motors as well as single- and three-phase induction motors can be used. The performance of the overall electro-mechanical system made by the motor and the associated driving circuitry – commonly referred to as a drive or inverter – depends on the motor control technique as it is a decisive factor in enabling accurate speed, torque and position control.

ST offers an extensive range of 8-bit STM8 and 32-bit STM32 microcontrollers, a wide range of power discretes including IGBTs and Power MOSFETs as well as integrated power modules (IPM) to help build scalable, high-efficiency power stages with power ranging from a few watts up to tens of kilowatts.

Additionally, ST provides an extensive portfolio of high-performance operational amplifiers and comparators, switching and linear regulators and MEMS inertial and environmental sensors – to enable predictive maintenance – and a comprehensive range of software and hardware evaluation tools to help reduce development time and cost.
