Abstract
A drive assembly for an electrical switching apparatus racking assembly is provided. The drive assembly includes a positioning assembly, a motor assembly, and a control assembly. The positioning assembly is structured to impart movement to said carriage assembly and to move said carriage assembly from said first position to said second position. The motor assembly is structured to impart movement to said positioning assembly. The control assembly is structured to control said motor assembly. The control assembly is in electronic communication with the motor assembly. The motor assembly is operatively coupled to the positioning assembly.

A drive assembly for an electrical apparatus racking assembly, said racking assembly including a carriage assembly structured to be movably disposed in an electrical apparatus housing assembly, said carriage assembly structured to be moved between a first position and a second position, said housing assembly including a number of sidewalls defining a substantially enclosed space, wherein said motor assembly includes an electric motor including a power line and a rotating output shaft, said drive assembly comprising:
- a positioning assembly, said positioning assembly structured to impart movement to said carriage assembly and to move said carriage assembly from said first position to said second position;
- a motor assembly, said motor assembly structured to impart movement to said positioning assembly;
- a control assembly, said control assembly structured to control said motor assembly;
- said control assembly in electronic communication with said motor assembly;
- said motor assembly operatively coupled to said positioning assembly;
- said control assembly includes a control circuit, an output assembly and a number of sensors;
- said control circuit in electronic communication with said output assembly, said number of sensors, and said motor assembly;
- said control circuit structured to control said motor assembly;
- said number of sensors include a current sensor and a torque sensor;
- said current sensor structured to detect a current and to provide an output signal relating to said detected current;
- said current sensor coupled to, and structured to detect the current in, said electric motor power line;
- said torque sensor structured to detect the torque in a rotating shaft and to provide an output signal relating to said detected torque;
- and
- said torque sensor coupled to, and structured to detect the torque in, said electric motor output shaft.
A drive assembly for an electrical apparatus racking assembly, said racking assembly including a carriage assembly structured to be movably disposed in an electrical apparatus housing assembly, said carriage assembly structured to be moved between a first position and a second position, said housing assembly including a number of sidewalls defining a substantially enclosed space, said drive assembly comprising:
- a positioning assembly, said positioning assembly structured to impart movement to said carriage assembly and to move said carriage assembly from said first position to said second position;
- a motor assembly, said motor assembly structured to impart movement to said positioning assembly;
- a control assembly, said control assembly structured to control said motor assembly;
- said control assembly in electronic communication with said motor assembly;
- said motor assembly operatively coupled to said positioning assembly;
