A specification sheet can tell you that a motor controller handles 48 V and 60 A, but it will not tell you how the motor sounds at walking speed, how much torque ripple your robot chassis will feel, ...

Picture an electric motorcycle holding position on a steep ramp while carrying a passenger. A speed controller holds a low target speed, yet a small throttle blip can turn a controlled launch into a ...

Imagine a brushless motor spinning at full speed, then the power stage suddenly switches off. The rotor continues to turn, and the motor terminals still show a voltage. That voltage is back electromo...

Why BLDC Motors Need Active Speed Control A brushed DC motor slows down or speeds up in a fairly direct way — change the voltage across the brushes, and the motor responds. A brushless DC (BLDC) moto...

The Simplicity and Reliability of Hub-Drive Systems A hub-motor integrates the electric drive directly into the wheel hub, eliminating the need for chains, belts, or complex transmission systems. Thi...

What Makes a BLDC Motor "Pancake" Shaped A pancake BLDC motor gets its name from its proportions, not its function. Instead of the tall, cylindrical "soup can" shape of a conventional motor, it's fla...

What Is a Hall Sensor in a BLDC Motor Pull the end cap off most brushless DC motors and you'll find three tiny components clustered near the windings, each barely larger than a grain of rice. Those a...

How an ESC Lets Arduino Control a BLDC Motor An Arduino can't drive a BLDC motor's three phases directly — it doesn't have the current capacity or the commutation logic built in. That job falls to th...

Why Mid-Drive Motors Are Superior for Performance Mid-drive motors are widely regarded as the optimal choice for serious cyclists and off-road enthusiasts because they leverage the bicycle’s existing...

CANopen Gains Ground in Industrial Motor Control Across factory floors, autonomous mobile robots, and electric vehicle platforms, one communication standard keeps showing up: CANopen. Once considered...

Why Ethernet Has Replaced Legacy Fieldbus in Motor Control For two decades, RS-485-based protocols like Modbus RTU and CANopen dominated motor control communication. They were reliable, deterministi...

What a Torque Motor Controller Actually Does Speed and position often get the most attention in motor control discussions, but torque is the foundational variable — the one that determines how much r...
