BLDC motors

The low-price electronically commutated 3-phase brushless motors (EC motors) are ideally suited for applications with highly smooth operation and service life. The highly energetic permanent magnets enable high acceleration and speeds of up to 14,000 rpm with excellent efficiency. The rotor position is fed back electronically via three 120° offset Hall sensors. Optional encoders to 1000 pulses/rev. enable high-resolution positioning controls.

Advantages

• Significantly higher efficiency and power density than induction motors (by approx. 35% volume and weight reduction at the same load)
• Longest expected service life and quiet running in brushless technology with precision ball race
• The linear torque characteristic allows an extremely wide speed range at full motor power, and hence better coordination to the required load conditions
• Reduced electrical interference radiation with good thermal properties at the same time
• Mechanically interchangeable with stepper motors, and hence less construction expense and greater parts variety
