Direct Drive Rotary Turn Table - Ironless - Coreless Drives:
Series ACD / ADR is a small rotary stage using direct drive, brushless motor technology. It has a diameter size of at least 62 mm and a centre through hole. The motor design is coreless, giving smooth motion even at low speeds. It also gives a relatively high torque. The encoder is also of high resolution. Hall sensors are integrated, so low cost drivers (trapezoidal commutation, current mode) can be used. This product can replace rotary stages using worm gears with stepper or servo motors. In addition to improvements on speed an accuracy, the ACD/ADR series offers a more compact design.
