For applications where variable speeds are essential, typically an AC electric motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option because of their wide swiftness range, low warmth and maintenance-free procedure. Stepper Motors offer high torque and simple low speed operation.
Speed is typically controlled by manual operation on the driver or by an external switch, or with an exterior 0~10 VDC. Velocity control systems typically utilize gearheads to increase result torque. Gear types range from spur, worm or helical / hypoid based on torque needs and budgets.
Mounting configurations differ to based on space constraints or design of the application.
The drives are high performance and durable and show a concise and lightweight design.
The compact design is manufactured possible through the combination of a spur/worm gear drive with motors optimized for performance. That is accomplished through the constant application of aluminium die casting technology, which guarantees a high amount of rigidity for the gear and motor housing at the same time.
Each drive is produced and tested specifically for each order and customer. A sophisticated modular system allows for a great diversity of types and a maximum amount of customization to customer requirements.
In both rotation directions, described end positions are guarded by two position limit switches. This uncomplicated alternative does not only simplify the cabling, but also makes it possible to configure the end positions quickly and easily. The high shut-off precision of the limit switches guarantees safe operation shifting forwards and backwards.
A gearmotor provides high torque at low horsepower or low rate. The speed specifications for these motors are regular speed and stall-rate torque. These motors use gears, typically assembled as a gearbox, to lessen speed, making more torque obtainable. Gearmotors are most often used in applications that require a lot of force to go heavy objects.
More often than not, most industrial gearmotors use ac motors, typically fixed-speed motors. Nevertheless, dc motors can also be utilized as gearmotors … a lot of which are used in automotive applications.
Gearmotors have numerous advantages over other types of motor/gear combinations. Perhaps most importantly, can simplify design and implementation through the elimination of the stage of separately designing and integrating the motors with the gears, therefore 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 optimum power management and use.
Such problems are common when a separate engine and gear reducer are connected together and lead to more engineering time and cost as well as the potential for misalignment causing bearing failure and ultimately reduced useful life.
Developments in gearmotor technology include the usage of new specialty materials, coatings and irrigation gearbox bearings, and also improved gear tooth designs that are optimized for sound reduction, increase in strength and improved life, which allows for improved performance in smaller packages. More following the jump.
Conceptually, motors and gearboxes can be combined and matched as had a need to best fit the application, but in the finish, the complete gearmotor may be the driving factor. There are a variety of motors and gearbox types which can be combined; for example, a right position wormgear, planetary and parallel shaft gearbox can be combined with long lasting magnet dc, ac induction, or brushless dc motors.
