For applications where adjustable speeds are necessary, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide swiftness range, low high temperature and maintenance-free procedure. Stepper Motors provide high torque and simple low speed operation.
Speed is typically managed by manual operation on the driver or by an external switch, or with an external 0~10 VDC. Acceleration control systems typically make use of gearheads to increase result torque. Gear types range from spur, worm or helical / hypoid depending on torque demands and budgets.
Mounting configurations vary to depending on space constraints or design of the application.
The drives are high performance and durable and feature a concise and lightweight design.
The compact design is made possible through the mixture of a spur/worm gear drive with motors optimized for performance. That is achieved through the consistent application of aluminium die casting technology, which guarantees a high amount of rigidity for the gear and motor housing concurrently.
Each drive is irrigation gearbox produced and tested particularly for each order and customer. A advanced modular system allows for a great diversity of types and a maximum degree of customization to client requirements.
In both rotation directions, defined end positions are safeguarded by two position limit switches. This uncomplicated remedy does not only simplify the cabling, but also can help you configure the end positions quickly and easily. The high shut-off accuracy of the limit switches guarantees safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low speed. The speed specs for these motors are regular speed and stall-velocity torque. These motors use gears, typically assembled as a gearbox, to lessen speed, making more torque offered. Gearmotors are most often used in applications that need a lot of force to move heavy objects.
By and large, most industrial gearmotors use ac motors, typically fixed-speed motors. However, dc motors can also be used as gearmotors … a whole lot of which are used in automotive applications.
Gearmotors have several advantages over other styles of motor/gear combinations. Perhaps most importantly, can simplify style and implementation by eliminating the step of separately developing and integrating the motors with the gears, hence reducing engineering costs.
Another benefit of gearmotors is definitely that having the right combination of electric motor and gearing can prolong design life and invite for maximum power management and use.
Such problems are normal when a separate engine and gear reducer are linked together and result in more engineering time and cost and also the potential for misalignment leading to bearing failure and ultimately reduced useful life.
Developments in gearmotor technology include the usage of new specialty materials, coatings and bearings, and also improved gear tooth designs that are optimized for sound reduction, increase in power and improved life, all of which allows for improved performance in smaller packages. More following the jump.
Conceptually, motors and gearboxes can be blended and matched as needed to greatest fit the application form, but in the end, the complete gearmotor may be the driving factor. There are a variety of motors and gearbox types which can be mixed; for example, the right position wormgear, planetary and parallel shaft gearbox could be combined with long term magnet dc, ac induction, or brushless dc motors.
