A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the powertrain and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network ...
The Start switch will then open and the motor will be at operational speed; Since 1920, the autotransformer starter has been the most popular device for reducing the starting current inrush for induction motors; it provides maximum starting torque with minimum line current.

Self-starting polyphase induction motors produce torque even at standstill. Available squirrel-cage induction motor starting methods include direct-on-line starting, reduced-voltage reactor or auto-transformer starting, star-delta starting or, increasingly, new solid-state soft assemblies and, of course, variable frequency drives (VFDs).

Fletcher Loyer scored 24 points on 8-for-10 shooting, including 4-for-6 from beyond the arc, to lead No. 20 Purdue to an 81-61 win over Minnesota in a Big Ten Conference matchup on Thursday night ...
Since the start of the year, 158 companies have gone public in the US via a traditional IPO — a 35% jump compared to 2023, according to Dealogic data.
Timothée Chalamet, Edward Norton and other stars of Bob Dylan film "A Complete Unknown" spent months learning to sing and play to re-create the past.
An automobile starter motor (larger cylinder). The smaller object on top is a starter solenoid which controls power to the starter motor and engages the Bendix drive.. A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power.
An induction motor draws very high starting current during its acceleration to full rated speed, typically 6 to 10 times the full load current. Reduced starting current is desirable where the electrical grid is not of sufficient capacity, or where the driven load cannot withstand high starting torque.
