Abstract
A method of stopping a reciprocating pump for hydraulic fracturing includes reducing speed of a motor in a first mode in which a speed demand is reduced over a first time period and a torque limit is held constant over the first time period; and further reducing speed of the motor in a second mode in which the speed demand is held constant over a second time period and the torque limit is reduced over the second time period. The motor comes to rest during or after the second time period. The motor is mechanically coupled to a reciprocating pump.
