Performance & Reputation

“Spin Down” Time: These machines have significant rotating mass; it is common for a GMF Senior to take several minutes to come to a complete stop after being turned off.
Legacy: GMF was eventually acquired by Betts Electric Motors in the early 1980s. Collectors and restorers highly value these vintage units for their smooth operation and reliability.
