TOPS supply a wide variety of drive electronics and controllers. Controllers are available from micro through to kilowatt ranges for both A.C. and D.C. devices. The controller is a link interface between the supply line work and the devices such as electric motors/machines.

BLDC control

Once you have decided what the controller has to achieve, it is then possible to start reviewing the performance and design of controller most suitable for your installation.
It may be that a controller contained on one circuit board would be sufficient for your application; or you may need complex controllers for a complete system including: networks, operator interface, workstations, integrated process controllers, remote operation, reporting, libraries and a full range of I/O distribution. If you provide us with your system architecture, we will assist you with your controller selection.

The drive products are divided into the following categories: industrial A.C./D.C. drives, stepper motor systems, servo motion controllers, motion control systems and drive software. Selecting a drive, we need to adapt to your machines or installation. We will need to know the number of motor shafts that you want to drive and their power rating (kW). The speed range and torque requirements would need to be established and, of course, any special requirements relating to environmental conditions.

Our experience – in many diverse applications, enables us to supply a drive controller with confidence, knowing that our products will meet your automation needs.

TOPS range of controls include:

• Stepper motor drivers
• Servo motor drivers
• Stepper and servo motor controllers

Stepper Motor Systems

Stepper motor controllers feature in a number of applications with the basic following engineering solutions:

Stepper drivers

• Rack/pinion type
• Belt type
• Cam type
• Leadscrew type
• Arm type
• Linear type

Our stepper motors can be driven from single IC devices through to multi-axis controllers.
The basic stepper motor driver requires a pulse generator which determines the motor speed and angle (deg°) of rotation, a driver that can switch the winding current in sequence and, of course, a D.C. power source.

To drive stepping motors at very low speed and with extremely minute angular increments, we provide microstepping drivers.

Microstepping functions by dividing the specified step angle further by increasing the current in one of the excited phases slowly and decreasing the current in the other phase gradually to provide a perfectly smooth rotation.

Servo Motion Controllers

A.C./D.C servo controllers are for use with motors and precision gear drives designed to function in automation and robotic applications. High performance is key to the "servo package" and normally the "servo controller" is part of a complete motion control package for both rotative or linear movements in a system, machine or robot complex.
