Abstract (en)
An elevator drive (9) comprising a motor (8) and a traction sheave (7) wherein the motor engages the traction sheave with a first coefficient of friction (µ1). Accordingly, as the motor (8) is frictionally coupled to the traction sheave (7), a degree of slippage or non-simultaneous rotation therebetween is facilitated.
