Which driver has high overload capacity?

Group drive has high overload capacity.

Which is more powerful motor AC or DC?

AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.

Which motor is superior in efficiency?

The inherent efficiency of a permanent magnet motor is higher than an induction motor. Both motors use a three-phase design through fully optimized performance.

What is group electric drive?

Group Drive : If several group of mechanisms or machines are organized on one shaft and driven or actuated by one motor, the system is called a group drive or shaft drive. Advantage : Most Economical.

What type electric drive is used in cranes?

variable voltage variable frequency. 10․ What type electric drive is used in cranes? Multimotor.

What is the maximum efficiency of an electric motor?

Most electric motors are designed to run at 50\% to 100\% of rated load. Maximum efficiency is usually near 75\% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor’s efficiency tends to decrease dramatically below about 50\% load.

Why are bigger motors more efficient?

The phase windings have higher resistance than high-power motors. There will be more force required for low-power motors with high speeds.
