Hi All, Someone told me today that as a general rule of thumb, motor idle current will increase as the motor nameplate speed decreases. In other words, a 3600 rpm (2 pole) motor might have 10-15% FLA at no load, an 1800 rpm (4 pole) motor might have 25-30% FLA at no load, and a 600 rpm (12 pole) motor might have 40 … WebSo, a 2 pole motor has more speed than a 4 pole motor. But, for heavy power, 4 pole motor is best than 2 pole motor. Gearbox below 3000rpm is always required for a 2 pole motor. On the flip side, Generally, there is no need for gearbox in a 4 pole motor. A 4 pole motor has double work output than a 2 pole motor. roblox work at a pizza place game
