6 FAQs about [Does a photovoltaic bracket require a permanent magnet motor ]

What is a permanent magnet motor?

Permanent magnet (PM) motors are available in alternating current (AC) and direct current (DC) and have significant efficiency advantages over AC induction and brushed DC motors. For AC applications, the rotor comprises windings for the induction motor, while the PM motor has permanent magnets affixed to the rotor (Figure 1).

What is a permanent magnet brushed DC motor (PMDC)?

Permanent magnet brushed dc motors (PMDC) are relatively efficient, easily controllable and, given the duty cycle for solar tracking applications, can be set up to last a long time (up to 5,000 hr continuous duty). This despite the brush or commutator wear that is inherent in their design.

What type of motor should a solar pump use?

Most commonly, a conventional brushed permanent magnet DC (PMDC) motor is used due to its simplicity of construction and low cost. However, such motors used for solar pumps suffered with the serious operational drawbacks such as ingress of working fluid inside the motor (in the rotor/stator) leaking through seal separating motor from the pump.

Is a permanent magnet AC motor better than an induction motor?

Benefits of Permanent Magnet AC Motors Because the Rotor in a PM motor doesn’t require any electrical current, it can be more efficient than an equivalent induction motor, as there will be none of the electrical losses that would be present in an induction Rotor.

Can a DC motor be operated by a solar pump?

For solar pump applications, a DC motor can directly be operated by PV module. However, in case of AC pumps, there will be an additional requirement of voltage inverter for converting DC to AC, thereby increasing the cost of installation.
