Stepper Motor Driver

ADI Trinamic's stepper motor drivers minimize overall power consumption and system cost by integrating everything into one single package – including predrivers, sensing, protection circuitry, and power bridges. Allowing for powerful, flexible designs with a high current profile that perfectly matches the motor, these stepper motor driver ICs greatly reduce design complexity and development time.

Microstepping for Smooth and Precise Movements

Stepper motors typically use a permanently magnetized rotor and motor coils as a stator. By sending an electrical current through the motor coils, an electromagnetic field is created that forces the magnetic rotor into the desired position. A typical hybrid stepper has 50 magnetic pol pairs that allow the motor to approach 200 full steps, meaning 200 positions per full 360° revolution. However, smaller steps like half steps or microsteps can be generated using additional current states. This increases the accuracy, torque, and efficiency of the motor while reducing step loss, vibrations, and noise.
