When designing a new piece of equipment that uses motors or gearmotors, design engineers must calculate how much motor torque will be needed to drive their application load. If the gearmotor or motor is undersized and too small, the product will be underpowered and likely not meet all application requirements. If the gearmotor or motor delivers more power and torque than required, then it adds unnecessary cost, requires more space and can negatively affect the total weight of the equipment.
Learn how to determine the actual load on a brushless DC motor or gearmotor by measuring the amount of current it draws. Step-by-step procedures explain how to compare motor torque calculations vs. real-world performance.
