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.

Smart. Efficient. Cool.

coolstep current adjustment points and thresholds

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.
