Haptic Drive with Auto Resonance Detection for Linear Resonance
Haptic Drive with Auto Resonance Detection for Linear Resonance

... Another common approach to driving DC motors is the concept of overdrive voltage. To overcome the inertia of the motor's mass, they are often overdriven for a short amount of time before returning to the motor's rated voltage to sustain the motor's rotation. Negative overdrive is also used to stop ( ...

Stepper motor



A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
