A variable speed gear motor is a mechanical device used to adjust and control the rotational speed of the motor according to actual usage needs. The device operates on mechanical principles, allowing flexible speed changes without the need for a complex electronic system. Thanks to its simple structure, high durability, and stable working capability, the mechanical speed variator (UDL) is often installed for motors in applications such as conveyors, agitators, mixers, industrial fans, and many other drive systems, especially suitable for harsh working environments.
The UDL variable speed gear motor is a line of mechanical drive equipment capable of flexible speed changes through a mechanical mechanism, helping to adjust operation without needing a variable frequency drive. The structure of the equipment is optimally designed to ensure durability, stable power transmission, and high working performance in various environments.
The UDL variable speed gear motor operates based on the combination of an electric motor and a stepless mechanical speed adjustment mechanism, allowing flexible speed changes right during operation.
When the motor starts, it creates initial rotational movement and transmits it through the gearbox to reduce speed while increasing torque. Then, this movement passes through the UDL mechanical speed variator, where the transmission ratio is changed thanks to a friction mechanism or disc-roller system, helping the output speed increase or decrease smoothly without stopping the machine.
During operation, when the operator turns the adjustment handle or adjustment mechanism, the contact distance in the transmission will change, thereby changing the output shaft speed as desired. This mechanism helps the equipment operate stably, reduces vibration, and is suitable for applications requiring continuous speed adjustment such as conveyors, agitators, or light production lines.
Variable speed gear motors are classified based on power source and power rating to suit each operational requirement and practical application in industry.
3-phase variable speed gear motor: Is a gear motor using a 3-phase power source, combined with a mechanical speed variator to adjust rotational speed flexibly during operation. This product line is suitable for industrial machinery systems requiring stable operation, uniform load, and continuous work capability for a long time.
Under 1.1kW variable speed gear motor: Often used for light to medium load applications, where simple speed adjustment is needed and excessively large torque is not required. This motor line is suitable for small-scale machinery, short conveyors, or mechanical equipment with limited installation space.
1.1kW to 3.7kW variable speed gear motor: Belongs to the medium power group, well meeting common industrial applications. The motor has stable load-bearing capacity, flexible speed adjustment, and durable operation, commonly used in industrial conveyors, agitators, mixers, and drive systems requiring high accuracy.
