Description
The CE108 Coupled Drives apparatus shows the problems of controlling speed and tension in coupled drives. Many applications use coupled drives, for example: magnetic tape drives, textile machines and paper mills.
The apparatus has two electric motors, coupled by a continuous fl exible belt. The belt also passes over a swinging arm with a ‘jockey wheel’ that measures the belt speed and tension. A manual control allows the user to adjust the spring tension at the swinging arm.
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 multivariable control systems.
Essential Base Unit
• Controller (CE120) – A controller with analogue and digital controls and instruments o r
• Digital Interface (CE122) – An interface which connects between most products in the Control Engineering range and a suitable computer (not included) o r
• Other suitable controller with +/– 10 V inputs and outputs
Both the CE120 and the CE122 include TecQuipment’s CE2000 Control Software (see separate datasheet) with editable, pre-made control experiments for use with the CE108.
Recommended Ancillaries
• Optical Tachometer (OT1)
Learning Outcomes
• Independent control of speed and tension
• Simultaneous control of speed and tension
• Practical methods of controlling multi-variable electromechanical systems
The flexible design of the equipment allows the user to develop many other analysis and control exercises to suit their needs. It is good for extended or advanced control experiments, and is ideal for student project work.
