We are offering 3-phase torque motor controller unit employed a solid state circuit. This solid state control circuit without relay provides high reliability as well as long and maintenance free service. The torque controller unit provides adjustable output ac voltage approximately 0 to 220Vac for each phase, hence the torque or the speed of motor can be adjusted. Torque motor controller mainly consists of 3 phase ONOFF switch, AC ammeter, potentiometer and control card.
