Amir Janjua, Technical Engineer at maxon motor UK & Ireland, outlines the options that are available for customers wanting a modified or custom motor controller.
In addition to offering a range of standard motor controllers, maxon also has a lot of experience in modifying and customising controllers to meet specific application requirements.
The current maxon catalogue range consists predominantly of the ESCON (Easy Speed Controller) and EPOS4 (Easy Positioning System), along with their variants EPOS2, EPOS2P and MAXPOS. The ESCON is a speed and current controller offering simple functionality via the use of analogue and digital inputs, and the EPOS range is a CANopen slave that operates as part of a communication bus system and requires control via a master.
If these off-the-shelf options are not suitable for the application, perhaps due to a hardware or firmware issue, they can either be modified or a custom controller can be designed.
In terms of the procedure of implementing a modification, a simple firmware update is required usually, and testing is executed and documented if required.
The extent to which maxon can modify existing products may be suitable for your application; however, if not, maxon offers custom options to suit.
Custom units are bespoke to the customer and the design; this means the drive can be optimised to every detail to ensure it is suitable for its purpose. Customisation can be offered for a variety of reasons, including:
Typically, the procedure of developing a customised controller is more thorough and more work is required, hence lead times can be longer; the following is a brief overview of what is required when designing a customised controller:
maxon motor produces DC motors, gearheads, sensors, controllers and accessories. With this in mind, the company can produce a complete integrated system that can be plugged straight into the final system. Offering an integrated system has many benefits, such as saving time from in-house assembly and having numerous suppliers. Having one supplier for the majority of components is efficient in terms of cost, time and traceability.
In the maxon catalogue, you can find motors with integrated electronics; however, if these do not have the required functionality, maxon can look into offering a bespoke system comprising a motor, a controller with necessary electronics and also a gearbox with any additional drive elements.
