Miniature Brake and Method of Assembly

A brake, comprising:

• a friction plate configured for coupling to a rotatable body for rotation with the rotatable body about an axis of rotation;
• a pressure plate disposed about the axis on a first side of the friction plate and fixed against rotation;
• an armature plate disposed about the axis on a second side of the friction plate;
• an electromagnet disposed about the axis on an opposite side of the armature plate relative to the friction plate;
• a spring biasing the armature plate in a first axial direction towards the friction plate and away from the electromagnet to engage the brake;
• and,
• a first fastener coupling the pressure plate to the electromagnet
• wherein the first fastener conforms to a first space between opposed surfaces of the pressure plate and the electromagnet and, upon hardening, bonds the pressure plate to the electromagnet
• wherein one of the pressure plate and the electromagnet defines a first recess and another of the pressure plate and the electromagnet includes a first arm extending axially into the first recess, the first arm defining first and second circumferentially spaced walls and the first recess defined by first and second circumferentially spaced walls configured to engage corresponding ones of the first and second circumferentially spaced walls of the first arm to inhibit relative rotation of the pressure plate and the electromagnet about the axis.
