Torque-speed requirements

Fulfilling the torque-speed requirements
If the selected torque motor cannot fulfill the torque-speed requirements, the following
options are available:
• Larger motor
If an operating point in the range A is required, a motor with a larger diameter and/or
longer length is required (see motor 2 in the following diagram).
Advantage: Higher torques are available.
Disadvantage: A larger motor installation space is required.
Figure 5-7
• Motor with faster winding
If an operating point in the range B is required, a motor with a lower voltage constant is
required (see motor 2 in the following diagram).
Advantage: Higher speeds are possible.
Disadvantage: A higher motor current is required.
