COTS
Our commercial-off-the-shelf (“COTS”) drive solutions have been designed to cover a wide range of applications in demanding end-markets. Our portfolio of more than 30 COTS standard motors comprises rugged inrunner BLDC motors from our NOVA and ADVANCE series as well as outrunner BLDC motors from our ORBIT series. Datasheets for all COTS motors are available. Lead times for our COTS motors are typically ~4-6 weeks.
MOTS
MOTS (“modified-off-the-shelf”) motors have the same mechanical parts as COTS motors but come with a customized winding. The winding of the motor determines the Kv (rpm/V) and allows for adapting the motor to the application requirements. Plettenberg offers MOTS motors with electrical design support from our engineering team, including an engineering study, which covers data sheets and performance simulations.
Fully Custom
If a MOTS solution is not sufficient and significant tailorization is required, a FC (“fully-custom”) solution is the best choice. FC drive solutions are often highly application specific and adjusted to complex requirements. Examples of customization options include:
- Custom housing and shaft
- IP67 rating
- Compliance with MIL-STD 810H or RTCA DO-160 requirements
- Special wrapping of magnets for ultra-high rpm applications
- Redundant winding solutions
- Ultra high/low temperature versions
- Frameless stator / rotor kits
- Single line replaceable units with integrated ESC
- Aerospace connectors
Plettenberg has more than 40 years of motor design and manufacturing experience, with proprietary design and simulation tools, which utilize a huge database of actual dyno measurements. This allows for highly accurate performance and thermal simulations of custom motor designs.
From our experience, most projects start with a COTS or MOTS solution, and progress to FC solutions as first data has been gathered and requirements become more rigid.
Key Benefits
Our drive solutions are made-to-order and can be tailored to the specific requirements of our customers. This can include adjustments to housing, shaft, number of poles, winding, cooling, IP rating, etc. These adjustments allow us to build the most efficient, lightest and robust drive solutions for our customers.
We take a holistic perspective and always look at total efficiency over the entire load profile. We tailor our products such that endurance and performance is maximized, and weight is minimized. Often, a tailored drive solution can increase efficiency by 15-30%, mitigate the need for gearboxes and reduce overall system cost.
All our drive solutions are developed and manufactured at our HQ in Germany. We employ highly experienced professionals with many years of experience. We believe in products built by hand, as it provides for the highest quality and a great degree of flexibility. We have a strict quality system which is EN 9100:2018 certified.
We support our customers throughout the entire product life cycle. Our engineers provide extensive development and system integration advise and support with prototyping. Following development, we manufacture the final series inhouse for as many years as required by our customers. We also offer an extensive spare parts program.
All our drive solutions are rugged in design and built for application in harsh environments. Our NOVA series of BLDC inrunners is available with ingress protection of up to 67. This makes them ideally suited for missions in the harshest environments, such as snow, desert or sea water operation.
We provide customers with tailored system solutions, comprising motor, ESC as well as related accessories. Next to the hardware, we provide extensive engineering and system integration support. In the case of starter-generators, we provide the generator as well as starter-generator electronic boxes.
