Abstract
It is described an orbital incubator shaker, which comprises an incubator housing (1) defining an incubation chamber (2), and an orbital shaker (3) configured to shake a shaking table (4). The orbital shaker (3) comprises a rotary direct drive motor (7, 8, 9, 10) comprising a stator (7, 8) and a rotor (9, 10) comprising a rotor shaft (9), and an eccentric bearing unit (11, 12, 14) mounted on the rotor shaft (9). The stator (7, 8) is located outside the incubation chamber (2) and the rotor shaft (9) extends from a space (22) outside the incubation chamber (2) towards the incubation chamber (2).
