Case Study of Grip Conveyor (Side Conveyor) Speed Adjustment
Issue
Operating 2 belts at a constant speed
Conventional Equipment
2 conveyors are driven by 2 three-phase induction motors to transport cylindrical loads (bottles, plastic bottles, etc.) between them (inverter is used for speed control)
- Application
- Printing and labeling loads
Conventional Problems
- Speed differences between belts causes the load to rotate, resulting in uneven printing and label application
- Three-phase induction motors are regulated via an inverter, but subtle speed adjustments are difficult
Solution
Brushless Motor BMU Series
for constant speed operation with digital settings and excellent speed stability
The brushless motor BMU Series provides precise speed setting and stable operation with less speed fluctuation. The speed difference between belts can be easily eliminated, improving load quality.
Specific Application Examples

Excellent Speed Stability
The speed regulation (with respect to load) is ±0.2 %*1.
For example, the speed range on the motor shaft at 3000 r/min setting is ±6 r/min. If 1/20 gears are used, ±0.3 r/min.
In addition to easily synchronizing the speed of multiple axes, stable operation is possible even when a wide variety of loads with different weights are transported.
Digital Detailed Speed Setting
Speed can be set digitally*2 in 1 r/min increments.
The speed of the 2 axes can be set accurately.
- *1
- When a three-phase induction motor is combined with an inverter, -15 % (reference value)
- *2
- Speed display and setting in conveyor speed (m/sec) is also possible
