For applications where variable speeds are necessary, typically an AC engine with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide rate range, low warmth and maintenance-free operation. Stepper Motors provide high torque and smooth low speed operation.
Speed is typically managed by manual operation on the driver or by an external change, or with an exterior 0~10 VDC. Rate control systems typically use gearheads to increase output torque. Gear types range from spur, worm or helical / hypoid based on torque needs 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 compact and lightweight design.
The compact design is manufactured possible through the mixture of a spur/worm gear drive with motors optimized for performance. This is accomplished through the constant application of light weight aluminum die casting technology, which guarantees a high degree of rigidity for the gear and motor housing simultaneously.
Each drive is produced and tested particularly for every order and customer. A advanced modular system allows for a great diversity of types and a maximum amount of customization to customer 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 makes it possible to configure the finish positions efficiently. The high shut-off accuracy of the limit switches ensures safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low swiftness. The speed specifications for these motors are regular speed and stall-speed torque. These motors make use of gears, typically assembled as a gearbox, to reduce speed, which makes more torque available. Gearmotors ‘re normally used in applications that require a lot of force to go heavy objects.
By and large, most industrial gearmotors use ac motors, typically fixed-speed motors. Nevertheless, dc motors may also be utilized as gearmotors … a lot of which are found in automotive applications.
Gearmotors have several advantages over other types of motor/equipment combinations. Perhaps most of all, can simplify design and implementation through the elimination of the step of separately designing and integrating the motors with the gears, thus reducing engineering costs.
Another benefit of gearmotors is certainly that irrigation gearbox getting the right combination of electric motor and gearing may prolong design life and invite for the best possible power management and use.
Such problems are normal when a separate engine and gear reducer are connected together and result in more engineering time and cost and also the potential for misalignment causing bearing failure and ultimately reduced useful life.
Developments in gearmotor technology include the use of new specialty materials, coatings and bearings, and in addition improved gear tooth styles that are optimized for sound reduction, increase in power and improved life, all of which allows for improved overall performance in smaller deals. More after the jump.
Conceptually, motors and gearboxes could be mixed and matched as had a need to greatest fit the application, but in the finish, the complete gearmotor may be the driving factor. There are many of motors and gearbox types that can be combined; for example, the right angle wormgear, planetary and parallel shaft gearbox can be combined with long term magnet dc, ac induction, or brushless dc motors.
