Custom Quality Torque Motors
Custom direct drive torque motor
tailored to your special application needs
Mosrac’s innovative stator and rotor design, combined with a skilled engineering team, allows standard motors to be customized for specific needs, even in small volumes at a reasonable cost. Custom frameless servomotors help customers gain a competitive advantage. We also developed multiple cooling options and can adjust connectors, shafts, and mounting to improve performance and efficiency.
Mosrac has developed custom motors with our customers for over 10 years, offering a range of shapes and sizes; see some examples below.
Custom Quality Torque Motors
Our dedicated engineering, design, and
sales teams
support you at 8 levels
General custom development stages
1. Gathering and analyzing requirements
Identify the specific needs of your application, such as load requirements, operational environment, space limitations, power, voltage, and performance criteria.
2. Defining the specifications
Defining specifications for customizing direct-drive torque motors involves several key details, including peak and continuous torque, speed, size, etc.
3. Conducting feasibility analysis & study
Conducting a feasibility analysis for customizing direct-drive torque motors involves evaluating technical, financial, market, and risk factors.
4. Concept Eng. & product development
Concept engineering for customizing direct-drive torque motors involves idea generation, concept selection, and preliminary design to explore feasible solutions.
5. Prototyping, testing, and design verification
Prototyping, testing, and design are key steps in frameless motor development. A prototype is built for early evaluation. Testing verifies performance, reliability, and compliance. Design verification ensures the final motor meets all requirements and is ready for mass production.
6. Trial-produce and mass manufacturing
Trial production and mass manufacturing are critical for making frameless motors and involve creating small batches to identify and resolve potential issues, ensuring design integrity and manufacturing processes, and then arranging the mass manufacturing.
7. Customized Packing and safe shipping
Packing and shipping are crucial for delivering frameless motors safely. Proper packing involves using protective materials to prevent damage during transit, selecting reliable logistics partners, and implementing tracking systems to ensure timely, secure delivery.
8. High-Quality Warranty and service
A comprehensive warranty provides assurance against defects and covers repairs or replacements. Excellent service includes responsive customer support, regular maintenance, and readily available parts.
