The MC73112, MC73112N, MC71112, and MC71112N from PMD are ICs that provide torque control with advanced features for FOC, shunt regulation, PWM (Pulse Width Modulation) signal generation with shoot-through protection, and more.
When it comes to step motors, a new drive technique called stepper servo has some engineers believing they have found the holy grail of positioning motion control - the high performance of a servo motor with the low cost of a step motor.
A noisy or chattering servo axis is perhaps the single most common motion problem that engineers encounter when building their motor-based machine. This deep dive focuses on servo motor noise problems and how to solve them.
Accurate velocity contouring for controlled coating thickness is critical and this use case looks at the considerations and then explains how to use high-performance motion control solutions to maximize uniformity of thin-film thickness.
Step motors are a common solution for controlling the position of moving components. This paper looks at step motor control design options and provides an in-depth review of a closed-loop motion control system.
This deep dive provides a detailed look at design choices, such as using off-the-shelf motion boards versus integrated machine control boards, for building a machine controller that provides advanced precision motion control.
