The SAT CONTROL SM4 BLDC-SL is a heavy-duty linear actuator specifically developed for solar tracking systems and other demanding outdoor positioning applications requiring high static holding capacity, reliable operation under wind loads, high-duty operation and long service life. The actuator combines a sensorless brushless DC motor, high-ratio planetary gearbox and a robust trapezodial stainless-steel spindle bronze nut transmission. The BLDC-SL drive eliminates mechanical brushes and provides substantially improved durability, thermal performance and duty-cycle capability compared with conventional brushed DC drives. The actuator has been specifically designed around the actual operating conditions of solar trackers – long periods of stationary holding, short tracking movements and occasional high transient loads caused by rapidly increasing wind conditions.<\/span><\/p>\n
