Dedicated Brushless DC Geared Motor for Pruning Shears Applications
Pruning is the most manual and time-consuming job in the viticulture and horticulture industries. When operator fatigue impacts productivity, efficient power hand tools are the solution to save time and ensure productivity levels are maintained. When compared to manual pruning tools, light and powerful motorized pruning shears help to reduce fatigue and repetitive motion injuries in many contexts such as viticulture, orchard and tree pruning, arboriculture and tree maintenance.

Understand What Factors Influence the Stall Torque of a Brushless DC Motor
Apply sufficient power to a brushless DC (BLDC) motor, and it turns. Remove the power, and it stops. But there is a condition in between where power is applied but the motor is not moving. This is a motor that is at stall. In this state, with power applied, it is very much a live motor; just because it isn’t turning doesn’t mean current isn’t flowing through the windings - actually just the opposite. At stall, an excess of current is flowing, heating up the motor coils; if stall conditions are maintained, or frequently repeated, these stresses can quickly add up to trouble.

Motor Technology Selection: Evaluation Factors
Motors are usually an indispensable element of an application’s motion system. However, selecting the motor is rarely straightforward. Motor technologies all have characteristics that can impact a design in different ways, and will determine whether you choose a brushless DC, coreless DC or stepper motor. Here are some key considerations to help you choose an optimal motor for your application.

Customized and Reliable Stepper Motors Address HVAC Damper Application Extremes
If you have to regulate HVAC system airflow on a constant basis, you’ll need automatic dampers with electric or pneumatic motors that can be controlled by a thermostat or building automation system. When designing an external mount electric damper actuator for an HVAC system, it’s important to review considerations in order to create the best motor-damper combination.
When evaluating a miniature motor to pair with an actuator, keep in mind that it may need to be customized. Ask yourself the following questions:

Improve Thermal Performance for Ironless Brush DC and Brushless DC Motors
Electric motor manufacturers must ensure that a motor’s instant internal temperature never exceeds its various components’ maximum allowable temperature. Depending on the design of the motor and the materials used, thermal phenomena will dictate the motor’s performance. Motor designers typically have two options to enhance motor performance without overheating and damaging its components: increase power conversion efficiency by generating less heat for a given mechanical power output or improve the motor's cooling capability through heat dissipation.

Efficiency and Power Density Redefined in Harsh Surgical Environments
Since the advent of civilization, the art of motion has been a critical part of human life in the quest to save, improve, and enhance lives. With advances in technology, motors are playing a very important part in our day to day lives, at times very subtly without our knowledge. Technology has helped improve motor power density and has enabled usage in various applications that once used pneumatic controls. OEM’s around the world developing motion applications in medical and industrial markets require the best power density, efficiency, and reduced envelope with lowered overall cost of ownership.
