Coupled Drives Apparatus

Model No: CNTLENG-05

Coupled Drives apparatus shows the problems of controlling speed and tension in coupled drives.
A manual control allows the user to adjust the spring tension at the swinging arm.
The apparatus has two electric motors, coupled by a continuous flexible belt.
The belt also passes over a swinging arm with a ‘jockey wheel’ that measures the belt speed and tension.
The basic control problem is to vary the torque in the motors to regulate the belt speed and tension.
The user guide also shows techniques for speed and tension control, simultaneous control of velocity and tension, and analysis of multi-variable control systems.
Many applications use coupled drives, for example: magnetic tape drives, textile machines and paper mills.
