<p>An apparatus (100) may include a working assembly (220) configured to perform a work function responsive to operation of the working assembly, an electric motor (230) that powers the working assembly, a power source (210) configured to selectively power the electric motor, a control circuitry (240) for controlling operation of the electric motor, and a brake function (270) configured to selectively apply braking to the electric motor responsive to a brake initiation event. The brake function may be configured to apply the braking by short-circuiting motor phase windings of the electric motor without requiring an external power supply during application of the braking.</p> |
