Abstract: An apparatus and associated method that contemplate a data storage disc and a motor supporting the disc in rotation. Control circuitry operates to spin up the disc drive by accelerating the motor to a steady state speed by: beginning the spin up by energizing the motor with a primary power; comparing an amount of auxiliary power that is available from a battery to a predefined threshold; and before the motor is accelerated to the steady state speed and if the threshold comparison is favorable, then boosting the primary power by discharging the battery for a predetermined boost interval.

Abstract: A method and system for reducing rollback in a counterbalancing system as a holding brake is released is disclosed. A limited amount of movement of a drive shaft is present in the holding brake. A motor drive provides current to the motor with the holding brake set such that a torque is applied at the drive shaft. The current is controlled to generate torque in both directions. The limited amount of movement in the brake may be used to determine a direction and magnitude of torque required to support a mechanical load being applied to the motor. The motor drive then provides a current to generate the necessary torque required to support the load prior to releasing the holding brake.

Abstract: The invention relates to a method and a control unit, which makes it possible to reliably detect in an electric vehicle whether or not an electric machine is in a blocked state. For this purpose, a current rotational speed of the electric machine (1) is monitored using a control unit (7). If a non-rotating state is detected, the electric machine (1) is actuated specifically for increasing a in torque. The current rotational speed is further monitored, in particular for an increase of the current rotational speed of the electric machine, at least a short-term one, for tensioning a drive train (3) against a wheel (5) blocked due to external influences, for example. If this is not the case, it is assumed that the electric machine (1) is blocked, and a corresponding blocking signal is generated. If the electric machine (1) is detachably connected to the wheel (5) via a coupling (19), it can be additionally provided that once the non-rotating state is detected, the coupling (19) is disengaged in order to see if the electric machine (1) will react to a request for an increased torque with an increased rotational speed, or if this does not happen due to a blocked electric machine.

Abstract: A device for improving efficiency of an induction motor that soft-starts the motor by applying a voltage to the motor that is substantially less than the rated voltage then gradually increasing the voltage while monitoring changes in current drawn by the motor, thereby detecting when maximum efficiency is found. Once maximum efficiency is found, the nominal motor current is found and operating ranges are set. Now, the voltage to the motor is increased/decreased by measuring the phase angle between the voltage and the current to the motor and increasing the voltage when the phase angle is less than a minimum phase angle (determined during soft-start) and decreasing the voltage when the phase angle is greater than or equal to the minimum phase angle as long as the voltage does not fall below a minimum voltage determined during soft-start.
