In the world of electric motors, two powerhouses have been competing for supremacy for the longest time: Alternating Current (AC) motors and Direct Current (DC) motors. Each of these motors has unique strengths, but one is stealing the spotlight and powering a brighter, more efficient future.
Let us delve into the key differences between AC and DC fan motors and why Steigen prides itself on integrating a BLDC motor with the Steigen technology.
Direct Current (DC) fan motor
DC motors are typically more expensive as they are known for their high efficiency, controllability, and starting torque. DC motors operate on direct current, maintaining a consistent flow of electrical energy. They excel in appliances requiring precise speed control, such as Steigen automated laundry systems! Hence, the system’s ability to maintain stable fan operation, low noise, and minimal wear and tear.
A Brushless Direct Current (BLDC) motor, as the same suggests, does not have brushes in the engine and uses electronic switching to control the current, which further eliminates energy loss. BLDC motors can also exert much more precise motion control.
Alternating Current (AC) fan motor
AC motors run on alternating current that periodically changes direction. Commonly used in household appliances (e.g. dryers and washing machines etc.), they are known for their simple construction.
However, they provide lower speed controllability and starting torque. Torque is the rotational force that gives rise to rotational motion. The less torque the motor produces, the weaker the ability to maintain speed control.
Benefits of BLDC motors
Longevity: Thanks to their robust design, BLDC motors offer a longer operational lifespan compared to traditional AC and DC motors. This translates to less downtime and lower replacement costs.
The durable motor construction also ensures it can withstand demanding work environments without compromising performance. Hence, the Steigen system’s ability to offer 3-hour and 6-hour Solar Drying modes. On the other hand, for AC motors, consistent 60ºC heat applied will weaken the stability resulting in breakdowns compared to DC motors.
Precise Speed Control: For Steigen automated laundry systems to provide a constant drying coverage evenly, BLDC motors that offer unparalleled precision to regulate speed are needed. It makes them ideal for tasks that demand accurate and responsive adjustments.
High Efficiency: BLDC motors boast remarkable efficiency, outclassing both AC and brushed DC motors in this regard. By eliminating the need for brushes (as seen in traditional DC motors), they reduce energy wastage and heat generation, making them an eco-friendly choice while significantly reducing electrical bills in the long run.
Compact Size: BLDC motors are impressively compact and lightweight. This advantage makes them a preferred choice where space is at a premium. That is why Steigen designed Solar Mini to provide compact systems for homes or service yards facing space constraints.
Quick Start and Stop: The Steigen 8-way Wind Direction alternates in a rotating direction, and a BLDC motor allows this flexibility while minimising technical issues.
In general, DC motors boast rapid start-up and braking capabilities. This quick response time is invaluable in scenarios where the motor needs to start, stop, or change speed rapidly.
Low Maintenance: BLDC motors are virtually maintenance-free. Without brushes to wear out, these motors can operate for extended periods without performance degradation or the need for frequent replacements.
Smooth and Silent Operation: BLDC motors operate with minimal noise and vibration. This silent prowess makes them an ideal choice for automated indoor drying racks where noise pollution is a concern.
Let the good times roll
While both AC and DC motors have their places in the world, BLDC motors shine in applications requiring precision, efficiency, and responsiveness. Their ability to deliver consistent power with minimal energy loss makes them the top choice for Steigen.
