Targeted increase in UPS reliability with PMDC motors
PMDC motors, as permanent magnet DC motors for UPS applications are an important component, critical for the function of UPS systems, especially in smaller systems or for cooling tasks. A fan failure can significantly shorten battery life due to overheating (e.g., by 20% in continuous operation under elevated temperature). This article highlights application areas and motor requirements depending on UPS topology. The motor selection is crucial. Basics of DC motors are relevant.
Different UPS systems present varying requirements. A permanent magnet DC motor for UPS applications in online double-converter systems (VFI) requires durability and high efficiency. In offline systems (VFD), the requirements for the motor are lower, as it is usually only active during power outages. Understanding these differences is important for a cost-efficient design. For specific applications, including servo motor applications, customization of the drive is necessary.Understanding PMDC motors: mastering function, advantages, and disadvantages
PMDC motors use permanent magnets, leading to compactness and often higher efficiency. These characteristics make them permanent magnet DC motor for UPS applications particularly suitable. The speed is proportional to the applied voltage, while the torque is proportional to the current. These linear properties render them suitable for precise control in UPS systems.DC gear motors provide further information.
- Utilize permanent magnets, resulting in compactness and often higher efficiency.
- Exhibit linear properties: speed proportional to voltage, torque proportional to current, ideal for precise controls.
- Offer high efficiency (often over 80%), which reduces energy consumption, heat generation, and component aging.
- Enable smaller UPS enclosures due to their compactness.
- Can exhibit high inrush currents, posing a demagnetization risk.
- Often require current limitation through a controller to protect the motor.
The advantages of such DC permanent magnet motors for UPS solutions in UPS systems include high efficiency (often over 80%), which reduces energy consumption, heat generation, and aging of components. Their compactness also allows for smaller UPS enclosures. However, high inrush currents can pose a demagnetization risk for the motor. Therefore, current limitation (e.g., through the controller model PDC-071-075) is important for motor protection.Control of DC motors is useful in this context.Optimally utilizing PMDC motors in UPS systems
PMDC motors cool batteries and electronics in UPSs by driving fans. Efficient heat dissipation through a reliable permanent magnet DC motor for UPS applications is crucial, as it can extend battery life by years, reducing costs and increasing availability. For specific voltages, 12V gear motors are available.
In larger UPSs (>100 kVA), PMDC motors for UPS applications also drive auxiliary pumps for coolant. Here, reliability and maintaining constant pressure are crucial. They also supply energy to critical subsystems: In case of a power outage, they ensure power for controls until the battery or generator takes over the supply.12V motors can serve in this context.Select suitable permanent magnet DC motors for UPS applications precisely
The correct selection of a permanent magnet DC motor for UPS applications is crucial for UPS performance. Rated voltage and rated current must be precisely matched to the requirements of the UPS system (e.g., 24V DC for fans, 180V DC for stronger drives). The ATEK motor PDC-071-075 is, for example, available in both voltages. Speed and torque must be appropriate for the task: fans require high speeds, while pumps need more power. Low-voltage DC servo motors provide details.
- Rated voltage and rated current must be precisely matched to the UPS system requirements.
- Speed and torque characteristics are critical for the specific task (e.g., high speed for fans, high torque for pumps).
- The environmental conditions at the installation site determine the necessary IP protection class of the motor.
- Design and mounting options (e.g., standard flanges like B5/B14) must match the mechanical integration.
- The availability of modular systems can facilitate adaptation to specific requirements.
- Optional features like encoders, temperature sensors, or holding brakes can enhance functionality and safety.
The environmental conditions at the installation site determine the necessary IP protection class of the motor (e.g., IP23 for clean environments, IP44/IP54+ for dusty or humid conditions). In selecting a permanent magnet DC motor for UPS applications the design and mounting options (e.g., IEC flanges B5/B14) must also match mechanical integration. Modular systems (e.g., from ATEK Drive Solutions) offer high adaptability. Options such as encoders, temperature sensors, or holding brakes can improve the functionality and safety of the drive. Permanent magnet synchronous motors are alternatives.Ensure compliance with UPS topology requirements for PMDC motors.
In offline UPS systems (VFD), cooling motors often operate only during a power failure. The requirements for lifespan and efficiency here are moderate, but reliability is very important. A motor with a S2-30 min duty cycle (e.g., the PDC-071-075) may be suitable here. permanent magnet DC motor for UPS applications, meist nur bei einem Netzausfall. Die Anforderungen an Lebensdauer und Effizienz sind hier moderat, jedoch ist die Zuverlässigkeit sehr wichtig. Ein Motor mit einer S2-30 Min. Einschaltdauer (z.B. der PDC-071-075) kann hier passend sein. Electric motors with brakes are available for special requirements.
Line-Interactive UPS (VI) activate the motor and the battery more frequently to perform voltage compensations. This requires a higher switching capacity of the motor and, in the case of brushed motors, a longer lifespan of the brushes. Online UPS (VFI), used for critical applications, impose the highest demands: continuous operation (S1), high efficiency, and reliability are essential here. Here, BLDC motors or special permanent magnet DC motors for UPS applications considerations.Profitably leverage future trends in PMDC motors for UPS
Although permanent magnet DC motors for UPS applications remaining relevant, brushless DC motors (BLDC) are increasingly gaining market share. Their advantage lies in their long lifespan, low maintenance effort, and energy efficiency, despite the more expensive control electronics. A transition to a 50 kVA UPS, for example, can double the maintenance intervals.
Intelligent motor controls for PMDC motors in the UPS sector enable precise control and integrate diagnostic functions for predictive maintenance, which reduces the total cost of ownership (TCO). Miniaturization through the use of neodymium-iron-boron magnets (NdFeB) increases power density and enables more compact UPS systems (for example, a motor that currently weighs 2 kg may weigh less than 1.5 kg in the future).
Optimally designed drives are crucial for UPS performance. The appropriate selection of a permanent magnet DC motor for the respective UPS application, tailored to the specific application and topology, ensures reliability and efficiency of the emergency power supply.
