Vessel VE-4500 Electric Torque Driver ไขควงทอร์คไฟฟ้าปรับแรงบิด

DESCRIPTION: 
Reliable operation, accurate adjustment, and easy maintenance...
VESSEL's uncompromising approach to the quality is reflected in every design.

The ergonomic design that reduces the burden on the worker during consecutive assembly and/or fastening work. Easy installation and wiring. Accurate torque adjustment. Maintenance-free concept. The VE series is an electric screwdriver for professional use that powerfully supports the production lines.

Slotless/Brushless Characteristics of motor:
Point 1 : Brushless motor is incorporated; long life and low noise

• A brushed motor requires replacement of brushes at regular intervals because the brushes wear out. A brushless motor is free from maintenance since the motor rotation is controlled by an inverter to suppress the abrasion. Also a brushless motor features low annoying sounds and low electrical noises.

Point 2 : Slotless structure enables smooth rotation without cogging torque

• Usual brushless motors generate cogging torque (uneven rotation) due to the magnet suction power between the rotor permanent magnet and stator core (iron core). Slotless structure resolves such cogging torque by air core coil not using an iron core.

Point 3 : Less heat generation and stable torque transmission

• Heat generation during motor actuation. Normally such heat remains inside the motor and influences the torque and the durability. In the slotless structure, however, coils are placed evenly along the inner periphery of the stator, which enhances radiation performance and suppresses efficiency loss caused by the electrical resistance fluctuation. 

Point 4 : Circuit design optimizing the motor performance

• It is necessary to stabilize the motor rotation at around 15000rpm for the stable output. By driving the motor with an inverter after detecting a position of the rotor magnetic pole wit Hall element, the motor rotates smoothly with little vibration and keeps optimal revolution speed.
