Which drive solution is right for your application?

The selection of a motor or drive system does not depend on a single key parameter. Installation space, continuous, peak, and holding torque, speed, dynamics, thermal behavior, sensors, gearbox, supply voltage, and planned production all collectively influence the appropriate design.

In our free Design Check, our experts discuss the requirements of your application with you. Based on this, we recommend the right motor series, size, and winding configuration, as well as a suitable integration concept if required.

For the initial inquiry, simply provide your contact information and a brief description of your project. The technical details will then be clarified personally by e-mail or phone.

FAQs about drive systems

Which drive systems does TQ-RoboDrive offer?

TQ-RoboDrive offers frameless motors as stator-rotor kits as well as custom actuators and integration services. With the ILM and ILM-E series, two motor platforms are available for different requirement profiles. Depending on the project, TQ can integrate not only the motor but also gearboxes, bearings, housings, sensors, and brakes, as well as handle assembly, testing, and quality assurance.

What advantages do frameless motors offer in drive systems?

Frameless motors enable compact drive systems with high torque density and great design flexibility. Since the stator and rotor are directly integrated into the mechanical structure, existing housing, shaft, and bearing structures can be used, and the motor, mechanics, sensor technology, and thermal connection can be precisely matched to one another. As a result, frameless motors are particularly suitable for applications with limited installation space and high demands on weight or integration.

Which industries are the drive systems from TQ-RoboDrive suitable for?

TQ-RoboDrive drive systems are used primarily in robotics, medical technology, industry, aerospace, and mobility. Depending on the industry, requirements differ significantly. In robotics, for example, torque density and dynamics are the main focus, while in industrial applications, precision and service life may be particularly relevant.

Can TQ-RoboDrive develop and manufacture custom actuators?

TQ-RoboDrive can, depending on the project, implement custom actuators based on a customer-provided design. Motor, gearbox, bearing arrangement, housing, sensors, brake, and other components can be integrated. The Assembly & Integration Service can additionally include component procurement, assembly, testing, quality assurance, packaging, and delivery. The exact scope of services is determined according to the requirements of the project.

How do I find the right drive system for my application?

The appropriate drive system is selected based on the complete technical requirements profile. Relevant factors include continuous, peak, and holding torque, speed, installation space, thermal performance, sensors, gearbox, supply voltage, and planned production quantity. In the free Design Check, the TQ-RoboDrive experts support the selection of the appropriate motor series, size, and winding configuration, as well as the evaluation of a suitable integration concept.
