The Benefits of Engineer-to-Engineer Collaboration in the Motion Control Industry

When you’re designing a device that requires a miniature motor, selecting a trusted and reputable motion control provider is absolutely crucial. One of the key qualifications to look for while vetting these suppliers is a focus on engineer-to-engineer (or E to E) collaboration! As its name would suggest, engineer-to-engineer collaboration is a process in which engineers representing both the motion supplier and the customer team up to actively design and develop the device, working together through the entire ideation to implementation process.

Understand What Factors Influence the Stall Torque of a Brushless DC Motor

Understand What Factors Influence the Stall Torque of a Brushless DC Motor

Apply sufficient power to a brushless DC (BLDC) motor, and it turns. Remove the power, and it stops. But there is a condition in between where power is applied but the motor is not moving. This is a motor that is at stall. In this state, with power applied, it is very much a live motor; just because it isn’t turning doesn’t mean current isn’t flowing through the windings - actually just the opposite. At stall, an excess of current is flowing, heating up the motor coils; if stall conditions are maintained, or frequently repeated, these stresses can quickly add up to trouble.
