DRIVE EQUIPMENT

Drive equipment consists of motor, control unit and belt. Ostberg provides easy, operationally reliable drive equipment for both constant and variable speed operation. Rotors are driven by a motor mounted on a bracket inside the casing. All rotors are driven by the motor via a belt to the rotor periphery. Rotors Ø<1400 mm are driven by round belts and rotors Ø>1400 are driven by V-belts. All motors are 4-pole with thermal protection.

Ostberg provides three-phase motor as standard, single-phase motor is optional. Belt pulley size and/or gearing are designed to achieve optimum rotor rpm. Optimum rotor speed for heat recovery is 12 rpm, and for moisture recovery (sorption rotors) 20 rpm.
