## How To Choose a Blender Watts - (Our Best Guide)

A 500 watt motor is sufficient for a typical blender workload. 1000 watt blender is the best blender for ice. It means the excessive the wattage the more powerful blender should be. Does Less Watts Mean Less Electricity? Lower watts mean less electricity. A 100 watt machine consumes less electricity as compared to 300 watt machines.

## Motor Poles & RPM - TW Controls

RPM = shaft rotation speed or revolutions per minute. Hz = frequency or cycles/sec. Poles = number of poles of your motor. So, for example, if you have a 4 pole motor on 60 Hz then RPM=60* (2/4)*60=1800 rpm. 60Hz is the most common frequency in the US. 50Hz is the most common frequency outside the US.

A four-pole motor will only rotate at 1,800 rpm. For 50 Hz motors, the speed is 3,000 rpm with 2 poles, and 1,500 rpm with 4 poles. The concept can be summarized with the following equation: Using this equation, a 4-pole motor at 60Hz has a speed of 1,800 rpm, while a 6-pole motor at 50Hz has a speed of 1,000 rpm.
