Linear motor commutation
Nettet12. jul. 2024 · What is commutation? In order to generate motion in a three-phase linear motor there must be switching between the phases to energize appropriate windings. … NettetStarting a free-piston linear engine-generator (LG) involves reciprocating a freely moving piston-magnet-translator assembly between two oppositely placed engine cylinders for combustion to occur. The machine is operated as a brushless linear motor to produce the required motion. However, due to the very large peak compression force during …

NettetThe LC linear motor utilizes a unique patent pending laminated steel core design. Coupled with the latest magnetic materials and optimized by 3D Finite Element … NettetFor linear Brushless motors it is generally not used, although it can be used as long as the index pulses are arranged so that each pulse occurs at the same phase angle within the commutation cycle. When using an index pulse the number of encoder counts per electrical cycle is not required to be an exact integer.
