Frameless Motor Specifications
NOTE: All motors are available in lamination stack length increments of 0.5 in. nominal. Only a representative sample is shown below. Many other designs are available. System performance will also depend on amplifier selection. Please complete enquiry form for further information and applications assistance.
Tc = continuous torque, Tp = peak torque
