Custom Motors Development

Rozum Robotics develops high-power custom motors to fit your requirements of a robotic design, automated line, or any other engineering project.

About Custom Motors Development

In engineering, motors play a critical part in the product’s overall success. While there are many drive options in the market, they often fail to satisfy clients’ demands of particular performance and dimensions. Understanding the need for made-to-order solutions, Rozum Robotics offers custom motors development services to its customers.

We can design and deliver any electric motor of your choice in full compliance with your timeline and budget. The customers are our primary focus. While we have several renowned products like RDrive Servo and FMI Frameless Motor that can be modified, we’re also adept at building new ones from scratch to provide custom-designed solutions easy to integrate into your application.

Rozum Robotics has been around since 2015. With our own R&D center, a team of accomplished engineers, and a number of breakthrough projects, we’re happy to accept any challenge and deliver a powerful yet low-weight motor exactly for your needs.

Case Studies

Read the stories of Rozum Robotics customers below to get an idea of what we’re capable of.

Case Study #1

The primary goal of the customer was getting two identical electric motors connected to each other, like a two-joint system, structurally reminding of a human elbow and wrist.

The technical requirements provided were as follows:

- distance between the centers of rotation of motors 100 mm
- maximum motor diameter 60 mm
- the motors supplied with rotor position sensors, temperature sensors, and a controller
- hollow shaft for routing wires through the device
- supply voltage 48V
- maximum speed of rotation of the output flange 85 rpm (at 30% of the peak torque)
- value of the peak torque 11 Nm
- degree of dust/moisture resistance IP61
- weight of the entire system no more than 1 kg
- service life 10 years

The results by Rozum Robotics: Electromagnetic, thermal, mechanical calculations were made. The design team prepared 3D models and drawings to show them to the customer. After that, all the necessary purchases were made and prototypes built on-site The works were performed in the shortest time possible—2.5 months.

The final product was the motors in the shape of a ball with a diameter of 60 mm to the customer’s satisfaction.

Case Study #2

The customer wanted five prototypes of an electric motor with non-standard dimensions: 60x60x156 mm and a mechanical interface for connection with the customer’s equipment. The motor also should have been compatible with the customer’s controller.

The technical requirements provided were as follows:

- the electric motor supplied with a rotor position and temperature sensors
- supply voltage 220V
- duty cycle - 180 ° for 0.3 s (under load), 0.6 s - pause
- operating mode S1
- value of the rated torque> 1 Nm
- degree of dust/moisture protection IP54
- weight no more than 1 kg
- service life 3 years

The results by Rozum Robotics: The team made all the necessary electromagnetic, thermal, mechanical calculations. 3D models and drawings were provided. After purchasing all the required materials and supplies, the in-house team built and tested prototypes. The whole process took less than 3 months.

The samples were handed over to the customer.

How It Works

Preparatory Stage

You reach out to us with your idea and list of requirements. After signing a contract, we start working on the development of a roadmap, risks checklist, project charter, and test plan.

up to 2 weeks

Concept Design

We undertake preliminary calculations and FMEA to come up with a concept for your idea, including the design of a motor, housing, encoder, and electronics. At this stage, we also select components for your approval and prepare technical documentation.

up to 10 weeks

Engineering Design

As we work on your custom motor, we complete the following technical calculations: statics, fatigue, vibration, torque curve, speed curve, capacity, efficiency, thermal calculations.

up to 8 weeks


Having an approved list of supplies, we start to purchase all the necessary materials and components, such as magnets, bearings, connectors, reduction gears, electronics parts, etc.

up to 8 weeks

Prototype Production

We get down to developing technical equipment for the custom motor prototype and then build up the prototype itself. As soon as the prototype is assembled, we hand it over to you for approval if requested.

up to 16 weeks

Testing and Documenting

After that, we test the protype assembled. We carefully document all the testing results as well as draw up detailed instructions and manuals for assembling and use of the custom motor.

up to 20 weeks

Pilot Batch Production

If there are no fine-tuning or modifications, we develop a pilot batch of your custom motors, test them, and send them over to you (up to 6 weeks). If adjustments need to be made, the timeline may be prolonged.

Top 5 Reasons to Order Custom Motor

Still not convinced? Here are more reasons to order a custom motor by Rozum Robotics:

In-House Production

All the motors by Rozum Robotics are built with our own hands. We do not outsource orders—every idea, motor, and robot is born in our R&D center.

Customized Solution

We are flexible and can easily adapt to your specific requirements and come up with a powerful yet low-cogging custom motor.

Simple Integration

Our drives are robust enough to be used in an industrial robot, yet compact and lightweight meaning you can use them for any design and any industry.

Live Tech Support

Our tech support specialists are ready to assist you whenever you need it. We also provide detailed documentation and video instructions for every product.

1-Year Warranty and Long Service Life

All our motors come with a 1-year warranty, boast of long service life and comply with the best industry practices.

Custom Motor Checklist

Struggling to put down the specifications for your idea? Go through our checklist for custom motors development:

What are your power supply parameters?
What is your nominal supply voltage?
What does your housing look like? What are the materials used?
What are overall dimensions (height-width-depth-weight)?
What are required motor characteristics (torque rating, voltage, rotation speed, etc.)?
What are environmental conditions the motor will have to operate under?
What you want your control system to be like?
Do you need temperature and/or speed sensors?
Do you have any additional requirements?
What’s your maximum planned budget?
