The last 30 year Biostat servo motor's and coupling's for the pharma business
The Biostat PCS (Process-Control-System) concept has since its introduction in the mid 1980ties been coupled to several servo motors brands. For small bioreactors and fermenters, like 1-20 liters WV. What´s shown below is the most well know.
Heidolph
B. Braun Biostat PCS was introduced 1986 and lasted until year 2001
Heidolph Electro GmbH is a part of Heidrive GmbH, Germany originating back to 1938. Presently offering a range of modern servo motors. Heidolph model 317 AC servo motor is a large and somewhat bulky setup supplied from 1986 to 2001 by Heidolph Electro GmbH. CerCell do not support the typical conical adapter concept on this servo motor. But an ID39-B adapter ring to mount / replaced the conical adapter on the servo motor is the option.
Kollmorgen
Sartorius Biostat PCS was introduced year 2001
Kollmorgen Seidel Servo Drives GmbH model 6SM compact AC synchronous servo motors exist in two variants (M or LL) lengths. Produced from 2001 and used on Biostat in limited numbers. Popular motor size is 6SM27 which has 55 mm frame size, OD40 mm support circle, lengths 142 or 172 mm, axle OD9 mm, flange bolt circle 63 mm and voltage ratings up to 480 VAC. Most 6SM servo motors are equipped with ID50-B adapter and magnetic power transfer coupling. A rubber seal is enclosed in the head plate of the UniVessel STR.
CerCell do not support this ID50-B adapter and magnetic coupling principle. But offer a replacement kit consisting of a new servo motor aluminum ID39-B adapter, new PowerGrip® ZN21 sprocket and SP21 polyurethane rubber coupling. Please check under "Conversion kits".
