The 23 and 34 frame motors are supplied with 8 flying leads for high flexibility on drive connection. This enables the user to connect motors in parallel, series and unipolar configuration.
The 42 frame motors have a terminal box and screw terminal connections. The 17 frame motors have 6 flying leads. All SD motors are manufactured by Sanyo Denki Co. Ltd. of Japan.
The motors are nominally 200 steps/rev (1.8 degree steps), although our drives are also capable of running in half, quarter or ministep resolution providing 400, 800 and 4000 steps/rev.
Depending on the electronic drive used, the steppers are capable of speeds from 0 to 3000 rpm, although torque is highly speed dependant. For further explanations and notes on stepper motor use see contact the office for our Stepper Motor Applications Guide.
The 'H' series have the same flange size as the standard series but have higher torque, higher efficiency and lower noise and vibration.The higher torque is achieved by higher efficiency magnetic materials.
The rotor inertia is also higher, making them better able to handle high inertia loads. They are ideal in applications where a standard motor of the same size has insufficient torque or safety margin. The cost however is higher than the standard series.
