    Abstract: An electric work machine (1) includes: a brushless motor having a stator disposed around a rotor (30); and an output part driven by the rotor. The rotor has a rotor core (31) and first and second magnetic-pole parts (34S, 34N) disposed around a circumferential direction of the rotor core. When the induced voltage of the brushless motor is given as Va, the power-supply voltage of the brushless motor is given as Vb, the rotational speed of the brushless motor is given as ω, a first induced voltage constant, which is expressed by Va/ω, is given as Ea [V/krpm], a pole-pairs count, which is the number of the first magnetic-pole parts or the second magnetic-pole parts, is given as Pi, and a second induced voltage constant, which is expressed as Ea/Pi, is given as Eb [V/krpm·pole-pairs count], the motor satisfies the condition: Eb≤0.025×Vb.

    Abstract: A powertrain, a coolant flow rate estimation method, and an electric vehicle are provided. Coolant in a first cooling loop of the powertrain is configured to cool an inverter. An electronic pump drives the coolant to circulate in the first cooling loop. When a phase current of a motor is greater than or equal to a preset current value, a controller determines a rotation speed of the electronic pump at a first moment as a first rotation speed, and determines a coolant flow rate at the first moment based on a temperature at a first position in the first cooling loop, a temperature at a second position in the inverter, and a power loss of the inverter. In the solution of this application, data does not need to be separately calibrated for different thermal management systems. This reduces time consumed by data calibration and improves practicability.

    Abstract: In accordance with at least one aspect of this disclosure, a system includes an airflow line, a main compressor disposed in the airflow line configured to receive a ram air flow and supply a compressed air flow to the air flow line, and a motor operatively connected to drive the main compressor. An air cycle machine is disposed in the airflow line downstream of the main compressor configured to receive the compressed airflow and supply a cooled cabin airflow to an aircraft cabin. A cooling line tap disposed in the airflow line downstream of the air cycle machine configured to communicate a flow of cooling air to the motor from the airflow line to supply a portion of the cooled cabin airflow to one or more portions of the motor as motor cooling air via a first cooling airflow line.
