CoolStep is a sensorless, load-dependent current control that uses stallGuard2™ load values. CoolStep maximizes efficiency by driving motors at optimal current.
coolStep™ is a sensorless load-dependent current control that uses stallGuard2™ load values. coolStep™ maximizes efficiency by driving motors at optimal current. Without the need for sensors, coolStep™ eliminates current security margin requirements, boosts the motor, avoids stall and step loss, and improves overall system reliability.
Stepper motors are widely used in consumer and industrial products, from low-cost printers to high-precision medical and laboratory instruments. They offer precise motion control but are not necessarily power-efficient. For example, biotech and medical equipment designers struggle to keep conventional stepper motor heat from damaging biological and chemical samples. Motors controlled with coolStep™, in contrast, can reduce motor heat dissipation by as much as 80%, improving equipment sensitivity and reliability.
