High on Hypoids
Trying to improve your overall efficiency? A high-efficiency NEMA premium motor helps only marginally if it is paired with an inefficient gearbox, such as a worm-gear drive. The motor is just half the equation - the gearbox is also critical. That's why, today, there is heightened interest in hypoid

DC Motors
brake. Dc motor speed can be controlled smoothly down to zero, immediately followed by acceleration in the opposite direction -- without power circuit switching. And dc motors respond quickly to changes in control signals due to their high ratio of torque to inertia. Wound-field dc motors

Mighty motors
Permanent-magnet synchronous motors eliminate gearboxes. Vice President and General Manager Industrial applications requiring high torque at low speeds typically use synchronous motors with reducers. Induction motors generate plenty of torque, but not at low speeds. However, new synchronous motor

Stepping Motors
. Damping may be required when load inertia is exceptionally high to prevent oscillation. Excitation modes:Stepping motors can be excited in different modes, depending on stator winding and desired performance. Two phase:One entire phase (stator winding) of the motor, end-tap to end-tap is energized

AC Motors
starting current, and low slip. This design is built to obtain low locked-rotor current. Both locked-rotor and breakdown torque are low. Normally used where starting torque is low and where high overloads are not imposed after running speed is reached. Wound-rotor motors: Squirrel-cage motors

Wheel may fly high
/epoxy composites for the flywheel's rotor, low-loss magnets for the bearings, high-speed electric motors and generators for energy conversion, and computer algorithms for motion control. This particular flywheel, enclosed in an aluminum vacuum vessel, consists of a high-speed brushless dc motor, upper
