Parts Feeder (Parts Supply Equipment) Case Study of Downsizing and Weight Reduction of Motor Section
Issue
Making the Motor Section Smaller and Lighter
Conventional Equipment
Equipment uses a three-phase induction motor to vibrate a feeder and orient a load in a certain direction before sending it to the next production process. (An inverter is used for speed control)
- Application
- Organizing and supplying springs, clips, etc.
Conventional Problems
- The motor’s L dimension is long, which limits installation locations for equipment
- The equipment as a whole is large and heavy, making installation and maintenance difficult
Solution
Brushless Motor BMU Series
A Smaller and Lighter Motor Section
The Brushless Motor BMU Series is used to reduce the weight of the motors. The smaller the motor, the greater the degree of freedom for equipment installation. The weight of the motor is also reduced as well, which makes for easier installation and maintenance.
Specific Application Examples
Contributes to the Downsizing and Weight Reduction of Equipment
Switching from three-phase induction motors to the BMU Series allows for the entire piece of equipment to be smaller and lighter.
This provides a greater degree of freedom with installation and increases work efficiency for installation and maintenance.
[Comparison of Dimensions and Mass (Round Shaft Type Motor)]
| Motor Appearance | Frame Size | Overall Length | Mass | |
|---|---|---|---|---|
| General Three-Phase Induction Motors 90 W |
 |
□90 mm | 135 mm | 3.2 kg |
| BMU Series 120 W |
 |
□90 mm | 50.4 mm Reduced by 84.6 mm | 1.2 kg Reduced by 2.0 kg |
A Fanless Design Prevents Dust Agitation
Because brushless motors do not have cooling fans, they do not stir up dust. This prevents foreign particles from contaminating and adhering to loads.
