To specify a motor optimised for an application’s speed and torque requirements, the motor manufacturer must work closely with the OEM, evaluating the implications of iron losses in order to create a design that limits their impact.
A key aspect of BLDC motor performance is efficiency – the ratio of the mechanical power output achieved from the electrical power input. An efficient motor design minimises heat generation, not only as this impacts power consumption, but also because it determines a motor’s physical space requirements.
A small footprint is key, but inefficient heat management can ultimately limit a motor’s speed and torque generation.
