Abstract

Provided is a motor. An electrically active part is provided with an insulating structure so that insulating properties between the electrically active part and one or more conductors near the electrically active part satisfy a certain safety standard regarding medical electrical equipment.

First claim

The invention claimed is:

1. A motor, comprising:
an electrically active part; and
an insulating structure for the electrically active part,
wherein the insulating structure provides insulating properties between the electrically active part and at least one conductor in proximity to the electrically active part that satisfy a safety standard regarding medical electrical equipment, wherein the safety standard is IEC 060601-1.

2. The motor according to claim 1 , wherein the insulating structure includes an insulator that satisfies the safety standard between the electrically active part and the at least one conductor.

3. The motor according to claim 1 , wherein the insulating structure provides a clearance distance and a creepage distance that satisfy the safety standard between the electrically active part and the at least one conductor.

4. The motor according to claim 1 , wherein the motor is a brushless motor including a stator core, and the electrically active part is a coil.

5. The motor according to claim 1 , wherein the motor is a brushless motor including a stator core, and the electrically active part is a coil.

6. An actuator, comprising:
a motor which includes:
an electrically active part; and
an insulating structure for the electrically active part,
wherein the insulating structure provides insulating properties between the electrically active part and at least one conductor in proximity to the electrically active part that satisfy a safety standard regarding medical electrical equipment, wherein the safety standard is IEC 060601-1, and
wherein the actuator is used in a drive mechanism of medical electrical equipment.

7. A medical support arm apparatus, comprising:
an arm unit that comprises a plurality of joint units; and
a medical tool on a front edge of the arm unit, wherein a joint unit of the plurality of joint units includes a motor of an actuator,
wherein the motor includes:
an electrically active part; and
an insulating structure for the electrically active part,
wherein the insulating structure provides insulating properties between the electrically active part and at least one conductor in proximity to the electrically active part satisfy a safety standard regarding medical electrical equipment, wherein the safety standard is IEC 060601-1.

8. The medical support arm apparatus according to claim 7 , wherein the joint unit comprises a movable mechanism including a stationary part and a movable part, and the motor is attached between the stationary part and the movable part without an additional interposing insulating structure.

9. The medical support arm apparatus according to claim 7 , wherein the medical tool on the front edge of the arm unit is an observation unit for observation of a surgical site.

10. The medical support arm apparatus according to claim 7 , wherein the actuator in the joint unit is driven by force control.
