Single phase motors are used primarily in small workshops and farms with a domestic supply. Some industrial equipment are specifically for use with a single phase electricity supply, such as fans, blowers, centrifugal pumps and high pressure washers.
Dependent on the application we are able to offer different types of single phase motors
Permanent Capacitor – PDA
Standard Design: Direct-on-line starting only, with any spot voltage between 200-250 volts available. Suitable for fans blowers and centrifugal pump drives with light starting requirements. Starting torque is between 25% and 55% of full load torque, according to frame size. Clockwise or anticlockwise rotation of the shaft is available by re-connection. Available in outputs from 0.09kW to 2.2kW, frame sizes PDA63S to 2-PDA90L, in 2 and 4 pole speeds.
High Torque Design: As above but with a higher starting torque of between 70% and 80% of full load dependent on frame size. Available in outputs from 0.37kW to 1.1kW, frame sizes 2-PDA80M and 2-PDA90L, in 4 pole speed.
Variable Voltage Speed Control Design: For use on variable voltage (thyristor) speed control such as fan applications. Available in outputs from 0.37kW to 1.1kW, frame sizes 2-PDA80M and 2-PDA90L, in 2 and 4 pole speeds.
Capacitor Start- EDA/TDA
Available in either Capacitor start/Induction run (EDA) design – vailable in outputs from 0.12kW to 1.5kW, frame sizes 2-EDA71M and 2-EDA90L, in 2 and 4 pole speeds, or Capacitor start/Capacitor run (TDA) design, available in outputs from 0.18kW to 3kW, frame sizes 2-TDA71M to 2-TDA100L, in 2, 4 and 6 pole speeds. Direct-on-line starting with any spot voltage between 200-500 volts available. High starting performances suitable for industrial and agricultural applications of a more demanding nature. Starting torque is between 160% and 300% of full load torque according to frame size. Clockwise or anti-clockwise rotation of the shaft is available by re-connection.
High Pressure Washer (HPW) – TDA
Direct-on-line starting only with starting characteristics to suit operastion from single phase socket outlets even when delivering 2.2kW. Motors are specifically designed to start under the worst possible conditions, i.e. against full back pressure, a condition which should not occurr but often does. Available in outputs from 0.75kW to 3kW, frame size 2-TDA100L, in 2 and 4 pole speeds. HPW motors are available with a standard shaft extension or with a female hollow shaft, having one bearing at the non-drive end. 110V versions are also available.
