Where Can I Find an Electric Motor with These Specific Requirements?

Click For Summary
SUMMARY

The discussion centers on finding an electric motor suitable for a low mass vehicle design with specific performance requirements. The desired specifications include a maximum torque of 110 Nm at 0-3000 RPM and a maximum power output of 46 kW (62 Bhp) at 5000 RPM, with a final drive ratio of 3.9:1. Participants emphasize the importance of closely matching these specifications to minimize overall vehicle and battery mass. A resource link to a motor specification database is provided for further exploration.

PREREQUISITES
  • Understanding of electric motor specifications and performance metrics
  • Familiarity with vehicle design principles, particularly for low mass vehicles
  • Knowledge of gear ratios and their impact on vehicle performance
  • Basic comprehension of torque and power calculations in electric motors
NEXT STEPS
  • Research electric motors that meet the specifications of 110 Nm torque and 46 kW power output
  • Explore the implications of different final drive ratios on vehicle performance
  • Investigate lightweight battery technologies to complement low mass vehicle designs
  • Review motor efficiency ratings and their impact on overall vehicle energy consumption
USEFUL FOR

Engineers, vehicle designers, and hobbyists focused on electric vehicle development, particularly those interested in optimizing motor specifications for low mass applications.

Ive been working on the design of an electric low mass vehicle. I have some requirements for the motor and was wondering if anyone knows anywhere i can find the specification of a motor that can meet the requirements?

The specs are;

1 forwward gear, Final drive ratio for diff = 3.9:1

Max torque = 110 Nm @ range 0ish-3000 Rpm
Max Power = 46 kW (62 Bhp) @ 5000 Rpm

Obviously the torque and power requirements are low and I am sure a lot of motors can supply this but i want one to match these requirements closely to keep mass down (along with battery mass).
